was a demo.? They had a couple of them and one had 40 miles on it and one had 3700 miles on it. We ended up taking the one with 3700 miles on it and it was only $3 cheaper. Now that I have a clear head and do the math I am wondering if I should have taken the one with 40 miles and paid the $3 more!?? I do not put a lot of miles on the car BTW. Can I just go in there on Monday and tell them I would like to switch cars if need be??
