Buying from a dealer vs a private seller
A private sale is usually cheaper. A dealer sale usually leaves you far better protected if something breaks. Here is exactly where the two differ.
The short answer
Buy privately if the price saving is large, you can inspect the car properly, and you can absorb a repair bill. Buy from a dealer if you want legal protection when the car turns out to be faulty — that protection is the main thing the extra money buys.
Side by side
| Dealer | Private seller | |
|---|---|---|
| Consumer rights | Car must be of satisfactory quality, fit for purpose and as described under the Consumer Rights Act 2015. | Only needs to be “as described”. Satisfactory quality does not apply. |
| Faulty car | Short-term right to reject within 30 days; repair or replacement after that. | No right to reject. Your recourse is a civil claim if the car was misdescribed. |
| Warranty | Often included, sometimes chargeable. Sits on top of your statutory rights. | None, unless manufacturer cover is still running and transfers. |
| Finance | Can arrange finance; Section 75 and finance-agreement protections may apply. | Cash or your own loan. No purchase protections from the seller. |
| Price | Usually higher — it covers preparation, overheads and the protections above. | Usually lower, with more of the risk sitting with you. |
| Checks done for you | Typically prepared, MOT'd and history-checked before sale. | Nothing is guaranteed. Do your own history check. |
| If it goes wrong | Complain to the dealer, then an ombudsman or trade body, then the courts. | The courts, and only if you can show the car was not as described. |
Where these rules come from
The difference in rights comes from the Consumer Rights Act 2015, which applies to sales by traders and not to private sales. Citizens Advice summarises how it works in practice for used cars, and GOV.UK lists the checks to do before you buy either way.
One catch worth knowing
Some traders pose as private sellers precisely to escape these rules — it is illegal, and it is common. If the seller has several cars for sale, will not meet at a home address, or is not the registered keeper on the V5C, you are probably dealing with a trader.
