Here is an excerpt from
Adviceguide from Citizens Advice about buying second hand cars privately.
Quoted below:
The vehicle doesn't match its description
If you can show that the vehicle did not match the description the seller gave you, you will have a claim against them, even if the seller believed the description to be true. It will strengthen your claim if you have written proof of the false description, for example, a newspaper advertisement. A false description which was only made verbally and not in writing will be much harder to prove, unless someone else was present who can act as a witness.
If the seller said something about the car which proves not to be true, for example, if they said that the vehicle had a new clutch or one owner from new, you will also have a claim against them. However, if the seller described the vehicle as in good condition, it will be more difficult to complain as the vehicle’s age, make and mileage, and the price you paid all have to be taken into account. If the seller did not say anything at all about the vehicle, you will not be able to claim against the seller.
If the seller sold you the vehicle as having an MOT certificate when it didn't really have one, you will have a claim against the seller.
If you want to take action against the seller because they gave you a false description of the vehicle or said something about it that wasn't true, you will need proof that the seller did this at the time of sale. If you have delayed for more than a few weeks or have used the vehicle a lot, this may be almost impossible to prove. An independent report may be able to establish the condition of the vehicle at the time it was sold, but this can be expensive.
If you want to complain about the vehicle not matching its description or the seller telling you something about the vehicle that isn't true, you should complain in writing to the seller. Ask them for a refund or for the cost of any repairs, depending on what you want them to do. If this does not succeed, your only other option is to take the seller to court. However, you should bear in mind that it can be especially difficult to get any compensation from a private seller.
If you are considering taking the seller to court, you should consult an experienced adviser, for example, at a Citizens Advice Bureau. To search for details of your nearest CAB, including those that can give advice by e-mail, click on nearest CAB.
