The tires where changed a month ago but they didn’t pick up on the buckled wheels was the fronts and they never picked up the arms or the movement how come !!!!! the mot runs out in October this year personally I’ll never get it back ? The trader has offered to share the bill £500 each but I’ve already spent £548 so gotta get a loan to pay for the next bill

I have bought what i thought was a amazing car which i had saved for , went to the car dealers house to view the car the car was warm when i had got there not such a problem i thought . the start up was noisy but was told it was the diesel rail (im no mechanic ) we paid for the car which was a bank transfer and off we went , The next day the car was cold and i had alot off steering wobble , told the dealer and he said he had driven it back from up north and the car was 100% and that he replaced 2 new tyres and brakes and a full service , after 2 weeks of arguing i decided ill get the wheels done £548 later 2 front arms replaced and 3 buckled wheels ......... no steering wheel wobble car was great , the noise from the engine after paying out investigations as the dealer said there are no fault codes its the cam chain tensioners and going to cost £1000 to fix the car was bought in end of july and the dealer will give £500 towards the bill ? is this fair
