I probably should have had it checked by a mechanic youre right,but I guess I got pressured by the fact that as I was returning from my first test drive there were already 2 other couples wanting to buy the car.Like I said I did pay $7000 less than wholesale and the car does run and drive great,the body is accident free and it was a one owner car,he did assure me that the oil changes were on schedule and most of the other repairs were done at shops other than Volvo and thats why his service book didnt have the stamps..??
