Practical guides for buying, selling and running a used car — and knowing its history before you commit.
Prefer to just run the reg? Our DVLA vehicle check shows a car's tax and MOT status, make, model and emissions for free, and the MOT check shows its full MOT test history. For wider context on what's actually on UK roads, see our UK car statistics.
Injured in a crash that wasn't your fault? If the injury itself is worth £5,000 or less, your route is the free Official Injury Claim portal rather than a law firm. A solicitor can still run it for you, but on a claim this size they are normally paid out of your compensation.
14 minSomeone has hit your parked car and driven off. The duty to stop was theirs, not yours, and the clock that follows is theirs too. This covers what the police and the Motor Insurers' Bureau will realistically do for damage-only cases, and what claiming on your own policy quietly costs you.
12 minThe other driver's insurer, a claims firm and a recovery truck can all reach you before your own insurer has even opened a file. Almost none of it is anything you have to engage with. This is what UK law actually asks of you after a crash, and what is only pressure.
12 minTwo windows in the year suit used car buyers, and they suit different ones. The weeks before a plate change bring discounted forecourt stock, so you get the choice. The weeks after bring a wave of part-exchanges, so you get the price. Timing buys you a cheaper car, never a sounder one.
7 minBuying a used car safely comes down to five things: a budget with headroom, a history check, an inspection, a test drive, and paying in a way you can prove. Miss one and you're relying on luck. The paperwork comes last, and it's what makes the car legally yours.
8 minAbout to go and look at a used electric car? Run every check you'd run on a petrol one, then four things a petrol buyer never thinks about: how healthy the battery is, what's left of its warranty, how you'll charge it, and the road tax it now pays. Take this list to the viewing.
10 minLoad a van past its payload and you risk more than a fine. It can invalidate your insurance if you crash over the limit. Payload and MOT class are the two things car buyers never deal with. The usual car checks still apply too.
7 minPay a dealer's higher price and the Consumer Rights Act 2015 comes with it, automatically. Buy privately and you save money, but you keep only a narrow set of rights. Price, warranty, part-exchange, finance risk and the scams all shift with the channel you choose.
8 minBought from a dealer and the car went wrong within weeks? The Consumer Rights Act 2015 gives you a refund, a repair or a price reduction. Which one you get depends on how long you've had the car. They come in a fixed order.
11 minUp to £3,750 comes off the price of a qualifying electric car, and you never have to claim it. The catch is the one most guides bury: it only ever applies to a brand-new car.
5 minDriving a car you don't own without cover is a £300 fine and six points, and the car can be seized on the spot. So sort the insurance before you touch the wheel. After that, work through what to look for, listen for and feel before, during and after the drive.
6 minRinging a seller about a car this week? Ask these questions in order. Some before you travel, some at the viewing with the documents in your hand, some during the drive, and some before you agree a price. Work through them and very little gets past you.
7 minHaggling on a used car works because most buyers don't do it well, not because prices happen to be soft. Research the fair price, bring evidence rather than a feeling, and be genuinely willing to walk. That works with a dealer or a private seller, and in any market.
6 minNo number is automatically too high. Mileage only means something next to the car's age and the life it's had, and the average car covers a little over 7,000 miles a year. Multiply from there, work out what counts as high for the age, then check the reading itself looks genuine.
7 minNo check catches everything. A repair the owner paid for privately, with no insurer ever involved, leaves no trace on any database. A paid history check will flag a formal write-off or a reported accident, and there's a fair bit you can spot yourself at the viewing for free.
6 minYes, you can legally buy and drive an imported car in the UK. The snag is that "imported" stretches from an EU-spec car near-identical to its UK twin, all the way to a 25-year-old JDM grey import that needed its own approval test. Work out which one you're looking at first.
7 minFour letters, and only two of them mean the car can go back on the road. Cat A and Cat B vehicles have to be destroyed. Cat S and Cat N can legally be repaired and driven again, which is why the letter on a listing matters as much as it does.
7 minA V5C proves who is responsible for a car, not who owns it. It stays silent on outstanding finance, write-offs and clocked mileage too. Check it properly all the same, because a VIN that doesn't match or a logbook issued last week tells you plenty.
9 minMost clocked cars give themselves away in one free check: hold the odometer reading against the car's MOT history. Do that before anything else. The other checks cost nothing too, and the law is on your side if you've already been stung.
7 minBikes are a bigger theft target than cars, and frame damage is far more likely to end in a permanent write-off. So run a check on the registration before any deposit changes hands. Then make sure the bike is legal on the licence you actually hold.
6 minBuy a car wearing a cloned plate and you can end up handling fines for roads you have never driven. Cloning copies a real registration onto a lookalike car, which makes it a different problem from theft or clocking. A few things at a viewing usually give it away.
7 minHand over cash for a car with finance still owing and the lender's claim follows the car, not the seller. On hire purchase, PCP and conditional sale, the finance company legally owns the vehicle until the final payment lands. Bought one already? You may well be protected.
8 minSince 26 August 2025, DVLA has run new rules for registering repaired, restored and modified vehicles. Like-for-like repairs mostly need no reporting now. Big structural changes and electric conversions do, so a rebuilt car should come with paperwork you can ask to see.
6 minYou can't run a registration through the police database yourself. A history check will surface a reported-stolen marker, and a handful of checks when you view the car catch most of the rest. Bear in mind that a check only shows what has been reported by the time you run it.
7 minElectric cars get written off after damage a petrol car would shrug off. The battery pack alone is often 30-50% of the value, and few insurers or bodyshops can safely assess a damaged one cheaply. A history check gives you the write-off category. It says nothing about battery health.
7 minThe free government check will not tell you whether a car has been written off. That sits on the insurance industry's register, along with outstanding finance and stolen markers. A paid check searches the registration for all of it, plus mileage. Run one before you pay, not after.
6 minNon-structural damage with the chassis left intact: that is a Cat N write-off, and it can legally be repaired and driven again. Plenty are perfectly sound and cheaper because of it. The marker still changes the sums on insurance, finance and what you get back when you sell.
8 minSeen "Cat S" on a listing? It means a load-bearing part, the chassis, frame or safety cell, took damage, and the insurer worked out a proper repair would cost more than the car was worth. Repaired properly, it's road-legal. Whether this one was is your question to answer.
7 minTwo drivers a mile apart, same car, same age, wildly different prices. Insurers treat the place your car sits overnight as a signal for how likely a claim is. This guide covers what your postcode really does to the number, what matters more than it does, and the levers a new driver actually has.
12 minTwo completely different tickets get called a parking fine in the UK, and their appeal routes don't overlap. Work out whether yours came from a council or a private operator before you do anything else, because the wrong route burns the only deadline you get.
13 minMost 2026 round-ups mix things that already apply with things that are still a consultation. Each change has the date it takes effect, with proposed rules listed separately.
5 minA Notice of Intended Prosecution is a warning that the police are considering prosecuting you. It isn't a conviction, and it isn't a fine. What the 14-day rule actually requires is narrower than most pages claim, and the separate section 172 notice stapled behind it is the one that can cause the most trouble if you ignore it.
12 minA private parking charge on a hire car or a dealer's courtesy car has only one statutory route to your door, and the law puts the parking firm on a tight clock to use it. The deadlines it has to hit are exact, and so is the paperwork that must exist before you owe anything.
12 minDVLA widened its online medical service in August 2026. Applying online is now up to ten days faster than posting a form. The bigger question sits behind it. Not telling DVLA about a condition that affects your driving can cost you £1,000. Most drivers have no idea whether theirs counts.
4 minBath's Clean Air Zone doesn't charge private cars. Not a penny, whatever the car's age or emissions. Vans, taxis, minibuses and lorries are the ones paying here, and the two daily rates are set out below.
6 min£8 a day, every day, if your car doesn't meet Birmingham's emissions standard. Most English clean air zones leave private cars alone. Birmingham's is one of only two that don't, so the car you're about to buy matters more here than almost anywhere else.
8 minBristol has no ULEZ. It has a Clean Air Zone, and that one does charge ordinary private cars £9 a day when they don't meet the emissions standard. Bath and Sheffield charge them nothing, which is where most of the confusion starts.
6 minRoad tax doesn't come with the car. Buy second-hand and the seller's tax is cancelled the moment the sale is registered, so you have to tax it in your own name before you drive away. No grace period. After that, the rates: what each band costs in 2026 and what changed on 1 April.
9 min"CAZ Class D exempt" turns up on sat-navs, road signs and council letters. It isn't a fine. It means the zone ahead can charge private cars, and that a vehicle has been marked as not paying. Whether that vehicle is yours is worth checking.
6 minLighting and signalling faults fail more cars than anything else, then suspension, brakes, tyres and visibility. That ranking comes from DVSA's own test data rather than garage folklore. Most of it is cheap wear you can spot on your own driveway a week before the test.
8 minTwo official payment services, not one. London's ULEZ is paid through tfl.gov.uk, while the seven English Clean Air Zones outside London all share a single gov.uk service. Miss the deadline on either and the charge turns into a penalty notice, which you can appeal.
5 minPicked up an advisory, or found a run of them in a car's MOT history? An advisory isn't a fail. It's the tester noting something that's wearing but still legal on the day. The pattern across several years tells you more, and reading it is a buyer's skill rather than a mechanic's.
8 minEvery item a tester checks comes from DVSA's own inspection manual. This checklist follows it chapter by chapter, so you can cross-check any car against the primary source. A pass only means the car met the legal minimum on the day it was tested, not that it's mechanically sound.
7 minSearch for new MOT rules and you will find plenty. Almost none of it changes anything for someone who just wants their car tested, and the change most people have heard about was rejected two years ago.
5 minDriving a car or motorbike into Sheffield? You won't pay a penny, whatever its emissions. Taxis, vans and lorries do pay though. This guide covers the rates, the exemptions, and how to check any vehicle before you commit.
7 minOff the road for a while? A SORN, or Statutory Off Road Notification, tells the DVLA that a vehicle isn't being used or kept on a public road. Declare one and you stop paying vehicle tax on it, and you stop having to insure it, for as long as it stays off the road.
7 minThree things decide whether a used car is legal on the road: a valid MOT, road tax in your own name, and a SORN if it's staying off the road instead. A fourth, ULEZ and Clean Air Zone charges, decides what using it costs. Each one gets a plain answer here, then a guide of its own.
11 minOne check won't cover them all. London has two schemes, ULEZ and the Low Emission Zone. England's cities have Clean Air Zones, and Scotland has its own Low Emission Zones. Four schemes, three checkers, and very different charges. Buy a car that's too dirty for where you drive and you pay every day you use it.
9 minGraduated driver licensing arrives in Northern Ireland on 1 October 2026. In England, Scotland and Wales there's still no such scheme, and no date for one. Which side of that line you're on comes down to where you're licensed.
5 minTwo years of R-plates, a six-month minimum learning period, night-time passenger limits: all of that is Northern Ireland only. Great Britain saw a much quieter set of changes to how you book and move your test.
11 minYour first quote came back costing more than the car. Putting a parent down as the main driver would fix that overnight. It would also be fraud, and it's the young driver who ends up uninsured.
6 minWhat actually goes wrong once a car passes eight or ten years old? No official table answers that. Some competitors present their own workings as DVSA data. This guide is built from what really is published: MOT failure records, a reliability survey, and the wear items that do go by age.
6 minIgnore the '40% in the first year' figures quoted all over the web, because nobody publishes a reliable number for that. What you can pin down is why some cars drop like a stone and others barely move.
8 minThe V5C records who the DVLA holds as the registered keeper of a car. Get that wrong and letters go to the wrong house: tax reminders, penalty notices, the lot. Updating it is free and takes a few minutes.
4 minYour car came back from the garage with the same fault still there. You aren't stuck paying up and shrugging, and you can't simply refuse the bill either. The Consumer Rights Act 2015 sets out what you can demand, and in what order.
10 minA full service history means every service the maker's schedule asked for actually happened. On time, with paperwork to prove it. It doesn't have to be a main dealer. No government database will confirm any of it. So a seller's word needs checking.
6 minRunning an ordinary used car costs anywhere from about £2,500 a year to £5,000 and up. Which end you land on comes down to insurance, fuel, tax, servicing and how fast it loses value.
12 minBuy from a dealer and the law already gives you free cover, before anyone sells you anything. A paid warranty sits on top of that, and only some of them are worth the money.
9 minSell your own car and you usually walk away with more than a trade-in pays you. The trade-off is that the vetting, the payment and the paperwork are all yours. Do it in the right order, know the scams, and know what you are still liable for once the buyer drives away.
11 minOnly one piece of paperwork is legally yours to deal with when you sell a car in the UK: telling DVLA you are no longer the keeper. The MOT certificate, the service history, a written receipt? All worth having. None of them required by law.
9 minThe gap between selling privately and part-exchanging is much smaller than the figures repeated across the internet. On some cars it even runs the other way. One properly sourced comparison exists, and this is what it found.
8 minReady to sell but unsure which route to take? Private sale, part-exchange, an instant-buy service and auction all pay differently, and they cost you different amounts of hassle. This guide covers what each one realistically gets you, the paperwork DVLA actually requires, and what the law says you must tell a buyer.
13 minA safety recall means the maker fixes a built-in fault, usually free. The catch is that a used car's new owner isn't contacted automatically. So checking is down to you, before you buy.
9 min
