I bought an 8 month old BMW 1 Series from a local car dealer in November 2016. There have been a few clues as to its history such as ill fitting door trims, paint drops on the off side doors and glass fragments on two inside window rubber trims. I took a good look at it over the weekend and have concluded the car has had a new off side wing mirror, driver's door and passenger door with the rear quarter being re sprayed. I've contacted the company but the owner is on holiday and I have emailed him this information and asked him to get back to me. What would be my rights in returning the car for a partial refund or exchange? I am also concerned that his accident will damage its value, invalidate its paint warranty and wasn't disclosed to me at the time of purchase.
