Took 4 hours to buy a car, when we bought my wife's last year at CarMax it took an hour. the car was scratched and dented... they repaired it but they should have caught it not me. I rolled in my sales tax and they never gave me the check... I didn't know I supposed to get one until I've waited an hour at the DMV and they tell me so... now I have to wait at the DMV again... car is nice but will probably not return to this dealer... the staff was nice but still had multiple problems that are very annoying.i doubt they do it intentionally which points to incompetence... not sure which I would rather have.
