I brought a car from a dealer, just under 2 months ago, since then its had numerous issues that didnt present themselves during the test drive, around a few weeks after purchase the car starts to misfire and judder, so repairs were done and it was cured for a few weeks, now the car is useless, engine lights on like a christmas tree, limp mode and the car misfires, and drives like rubbish, the garage have been helpful so far and paid for some repairs but ive also shelled out quite a bit, I just feel this soon into buying it and spending quite a bit of money buying the car, its not really ideal, ive lost all faith in the car now, what are my rights on the matter? thanks for any input.
