I'm frustrated with my visit. I want to buy a car in the next 2 weeks and I really like the look of the cars but worry about them being branded. Im not a mechanic but Ive always had junkers that I've had to work on. So, I can tell if a car has been fixed up well and wanted to stop by and do a couple test drives to settle my fears. Specifically how they worked on the frame and suspension in front end collisions. I was honest with the sales guy and he didn't want to show a car to someone who wasn't buying that day. So, I think I'm just going to buy new.
