How much is the car worth - how much has been financed? Put it down to bad experience or keep going.

Say the car was £1,500 but in its current state it's worth £750 get rid and get a car that is in better condition albeit older for the £750.

I believe you have 14 days with financial agreements unless you sign on their premises in which case the right is waived - however you would have to give the money back as I bet it aint finance I bet it's a loan. Might be the other way round but this is something to look into.

What ever you do - don't stop paying. The finance company/loan company/debt collectors wont give a shit about your story.

If you're going for sales of good act you must REJECT the item for failing to meet x y z standard and quote the part of the act you're going after - if you do not do this then you will get no where, it is prerequisite of the act.

List the faults - but bare in mind they must be faults, simply saying the car is scratched isn't a fault on a 2nd hand car.

You must do it at your first opportunity.

Remember you had the opportunity to inspect the item - if the item is sold at a reduced value because it carries certain faults you have no right to return or complain about buying it with faults unless those faults are clearly stated.

If the car is a decent value it may be worth an hour with a solicitor and a solicitors letter rejecting the car.
