Not hard to prove when the car is unusable. And you are well within the law to return it for a full refund So it's not myth it's fact Look up sale of goods act 1979 on the gov website You do have the right to return it if it had a fault
There is no MAY about it you CAN!
You can't that is a fact , here is the law verbatim
The law
When you buy a used vehicle from a trader you are making a legally binding contract. You have legal rights against the trader under the Sale of Goods Act 1979.
The vehicle should be:
- Of a satisfactory quality - free from minor defects, safe and durable for a reasonable length of time. When assessing satisfactory quality you should take into account the price you paid for the vehicle, its age, mileage and condition at the time of sale.
- Fit for its intended purpose or a purpose that you made known to the trader - fit to be driven on the road.
- As described - the vehicle should correspond with any description applied to it. In some circumstances, the trader may be liable for any statement made by the manufacturer of the vehicle.
If the vehicle is faulty , you are legally entitled to request one of the following remedies:
a full refund
compensation (damages)
repair or replacement
rescission or reduction in price
Note you are legally entitled to
request the dealer can tell you to fcuk off and there's no redress except to go to court. If you do you will be asked to prove the vehicle was not fit for purpose at the time of the sale, you might be able to prove it is not fit for purpose now if its broken down, but try and prove it was not fit for purpose at the time of the sale, you drove it home didnt you?
I've seen Trading Standards bring these to court many times and they have lost on every occasion
