CraigI think they might be leading you on. Tell them you are rejecting the car, period! If you allow them the opportunity to repair the car, you will compromise your right to reject it. You are on very complicated legal ground here, but you need to reject it, and NOT, repeat not, allow them the opportunity to repair it. Tell them they have identified the problem, they have told you it will happen again, that Mr X told you he would not put his own family in the car etc.. You MUST document all this in writing.I had a similar problem in the late 90's when I bought one of the first Mercedes M class. The car broke down 3 times on the first day, on the trip home from the dealer. I told them the following day that I was rejecting it. They offered a loan car whilst they investigated it. I told them I had lost confidence in the car (same as you), and they accepted my rejection.If you have finance on the car, then advise the finance company that you have rejected the car, as the dealer have confirmed it is unsafe.Good luck
