- I've deleted that one dups are a pain and it was in the wrong place really!
Just mention the words Sale and Supply of Goods Regulations. Trade Descriptions Act 1968. Road Traffic Acts
If you really like the car and want to keep it , then get the dealer to fix it, the dealer can't mess you about because you have consumer law on your side. If you can easily find a repalcement then demand a refund.
If the dealer is messing you about then go into your local CAB and they will deal with it for you.
Good luck and let us know how you get on.
