Running a car

What a used car really costs to keep on the road, which cars hold their value, and where you stand when a garage bills you for work that didn't fix it.

The cost of running a car arrives at different speeds, and the biggest one never sends a bill.

Fuel and insurance you feel monthly. Servicing arrives a few times a year. Depreciation takes the largest share of all and shows up only when you sell. Running costs of a used car puts numbers against all of it, and depreciation explained covers which cars hold their value and why.

Maintenance is where a used car is won or lost. Common faults by age sets out what tends to break and roughly when. What a full service history really means matters more than the phrase suggests. What happens if your car has a recall covers what to do next.

Then there's winter. Winter tyres in the UK covers the law and when they're worth fitting. Defrosting your car legally covers frosty mornings. Preparing your car for winter covers the rest.

Breaking down on the motorway sets out where to stop, when to get out and when to call 999. A flat tyre with no spare covers the repair kit, the space-saver and when to call for help.

Is my car compatible with E10 petrol? covers the official checker, the early-2000s cars that get caught out, and what to do if you've already filled up. Put the wrong fuel in? explains why you shouldn't turn the ignition on, and what to do instead.

The 2026 fuel duty rise explains why September's increase never happened, and what the rate is now.

Cover is the other half. Used car warranties explains the types, what they routinely exclude, and when one is worth buying at all.

Three more cover paperwork and disputes. Keeping your V5C updated covers the changes DVLA needs to hear about. When a mechanic didn't fix your car covers where you stand on a bill for work that didn't work. Can a garage keep your car if you don't pay? covers its right to hold the car, storage charges and when it can sell.

Signs a garage is overcharging you is the one to read before any money changes hands. Before you book, how to find a trustworthy garage explains what the main badges actually check.

Paying for the car is separate. HP vs PCP sets out how the two agreements differ, and what the balloon payment does to your right to walk away. Is 0% finance worth it? answers the other half. Car finance commission claims explains whether you could be owed money while the FCA scheme is paused.

Servicing raises two questions. How much should a car service cost? covers the price. Do you have to use a main dealer to keep the warranty? sets out what the competition rules protect.
