Can you return a used car to the dealer?

In one paragraph
Sometimes. A consumer buying from a dealer has a 30-day short-term right to reject a car that is not of satisfactory quality, under the Consumer Rights Act 2015. A car bought online and delivered also carries a separate 14-day cancellation right. Changing your mind about a car collected in person is not covered.
What does the law actually say about returning a used car?
The Consumer Rights Act 2015 says goods must be of satisfactory quality (s.9), and where a car sold to a consumer is not, the Act gives a short-term right to reject it within 30 days of delivery (s.22). That is a right about the condition of the car, not about taste. A car that is exactly as described, with faults a buyer was shown and a service history that matches, is not covered by it.
There is a second, separate route. Under the Consumer Contracts Regulations 2013 (regs 29–35), a distance or off-premises contract carries a 14-day cancellation right. That one is not about faults at all.
Can a used car be returned just because the buyer changed their mind?
Only where the sale was made at a distance or off the premises. Buying a car online and having it delivered is a distance sale, so the 14-day cancellation right in the 2013 Regulations applies. Walking onto a forecourt, driving the car and signing there is not a distance sale, and no change-of-mind right attaches to it.
A car bought from ONECARS online and delivered is a distance sale, and the fourteen days run from delivery.
What is the difference between rejecting a car and cancelling the contract?
Rejecting is about the car being faulty; cancelling is about how the sale was made. The 30-day short-term right to reject under s.22 of the Consumer Rights Act 2015 depends on the car not being of satisfactory quality. The 14-day cancellation right under the 2013 Regulations depends only on the contract having been made at a distance or off-premises.
The two can overlap on the same car. They are different rights with different conditions, and a dealer answering a return request has to work out which one is being used.
What happens if the dealer tries to repair the car first?
The Act allows one attempt. Under s.24(10)(b) of the Consumer Rights Act 2015, after one failed repair or replacement a consumer may reject the car, and a deduction for use may apply after the first six months. So a repair that does not hold is not the end of the road.
Does a fault in the first six months change anything?
It changes who has to prove what. Section 19(14) of the Consumer Rights Act 2015 says a fault found in the first six months is presumed to have been present at delivery unless the trader proves otherwise. After six months, that presumption no longer runs.
Does "sold as seen" mean a used car cannot be returned?
No, not where the buyer is a consumer and the seller is a dealer. Section 31 of the Consumer Rights Act 2015 says a trader cannot exclude or restrict liability for goods being of satisfactory quality, fit for purpose and as described. The phrase on the invoice does not remove those rights.
Who settles it if the dealer and the buyer disagree?
The Motor Ombudsman handles disputes about a vehicle sale, and the Financial Ombudsman Service handles complaints about credit. They are separate schemes, and a complaint about the car itself belongs with the first.
How does buying from ONECARS sit alongside all this?
The point is to need the law as little as possible, and that starts before the sale. Every ONECARS car is checked on 34 points by ONEFIX, our own workshop on the same site at Plas Acton, Wrexham — the list is published at /how-we-check-our-cars. Where a check leaves work outstanding, the car is not handed to its buyer until ONEFIX has put it right; that rule sits in the ONECARS system rather than in a salesperson's promise.
Every car page carries the car's photographs, its full spec and its MOT history, so the condition of a car can be read before anyone drives to Wrexham to see it. For a car old enough to have been tested, that MOT history comes from the DVSA, test by test, with the mileage recorded at each test — the same record anyone can pull free on GOV.UK from the registration number. The 2012 Vauxhall Astra 1.7 Club Ecoflex at £1,295 is a fair example of a car with that history on its page.
Three other things are worth knowing. A reservation holds a car for fourteen days, and within those fourteen days it can be cancelled for any reason with the fee refunded in full; go ahead, and it comes off the price. There is no admin fee — the price shown is the price paid. And every car comes with a free three-month warranty on the engine and gearbox, up to 2,500 miles, with repairs done by ONEFIX on the same site, with longer paid cover available. What it covers is set out at /guides/what-our-warranty-covers.
After the sale, ONEFIX next door services, repairs and MOTs the car, which means the people who checked it are the people who see it again.
What is worth checking before buying, so a return never comes up?
Read the record rather than the sales patter.
- Pull the MOT history free on GOV.UK from the registration and read the advisories, not just the passes.
- Check the mileage recorded at each test rises in a straight line.
- Ask who checked the car, on what list, and whether that list is published.
- Ask whether anything found at the check was put right before the car was offered.
- Check the V5C log book is there and the details on it match the car.
- Ask what cover comes with the car and what happens to it afterwards.
