My car, the problem

My grandmother found out through some of her friends who have purchased cars from that specific dealer that he is a bad dealer. He sold them cars with similar issues, such as the check engine light being on. Later on after driving the car for awhile, and his promise that he had the car checked out, their cars broke down and they had to spend hundreds to get the car fixed. So needless to say the man is not a reputable dealer and my grandmother does not want me to buy the car from him.

The car however has everything I want:its roomy, has all leather interior, power windows, power locks, power mirrors, CD player, and interior wood finish. It is exactly what I want down to a T, so I may still buy the car. However I would believe him more if he told me that there was a minor problem but they had it fixed no problem.
