Hi all, first time user so please be gentle, I'll try and keep this a short as poss, my problem was I bought a car from garage and needed to change over to a cherished number plate so the owner of the garage allowed me to have the new car along with log book 6 months tax new MOT and service he kept the car I P/X'ed. I had to send all paperwork off for both cars so this left me with the tax disc and log book for my old car. After having the new car for a week I noticed a knocking from the front passenger side when braking and after taking it to two different garages i was told the brake discs were warped and needed replacing. I phoned the owner of the garage straight away but could not get hold of him and found out he was away for two weeks on holiday. I needed the car fixed asap as i was about to go away myself and didn't want to drive a car on a 400mile round trip with a defect. I got the discs and pads replaced cheaply as poss as my brother is an ex-mechanic so labour was FOC but parts were £79, am I within my right to keep the tax disc from my old car to cover the cost of the parts, there is nothing on paper to say the car i part exchanged should have the tax with it. The owner of the garage has since phoned me from his holiday and said "no the car comes with the tax we had a deal, why didn't you take the car to the garage that just serviced it we will have to talk about it when i get back" I know that it is up to him to prove the fault was not on the car when he sold it but don't want any come back if i just send him the log book and mot certificate with no tax disc as i had to cover the cost of the parts. Hope this makes sense would appreciate any advice many thanks
