Private sale or part-exchange, what each is realistically worth, and the paperwork you have to get right when the car changes hands.
Almost every question about selling comes down to one trade-off. Selling
privately usually pays more, while part-exchanging is faster and much less
hassle.
The gap between them is smaller than people assume, once you count your own
time.
Which suits you depends on the car more than on you.
Part-exchange against private sale
walks through where the difference is worth having. Cheap, older and
high-mileage cars tend to close that gap, while clean and desirable ones widen
it.
If you go private, our
step-by-step guide covers writing an
advert that pre-empts the obvious questions. It also covers handling viewings
safely, and taking payment in a way that clears before the car leaves. Payment is where private sellers get hurt. Haste is usually why.
The paperwork is the part people get wrong, and it carries legal weight.
Telling DVLA the car is sold is your duty, not the buyer's. Doing it late is
its own problem, whatever the buyer does next.
The paperwork when selling lists
every document that has to change hands.
One thing is worth knowing before you advertise. A private seller isn't held to
a dealer's standard on quality. You are held to your own description, and
that's a lower bar to trip over than most people expect. A car described
accurately is much harder to complain about later.
Sell 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.
Only 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.
The 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.
Ready 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.
