The peeling paint on the windshield cowling isn't uncommon. When I went to Chicago to get my Dragon it had the same problem including some rust! Now consider this is a brand new vehicle with less than 10 miles on it. This piece is only a thin stamping but I ended up taking the other Dragon they had since I was driving back to FL.

As for the moonroof, if you think this may be "the one" go ahead and spring the $20 or so for the full CarFax. You get a bunch more info and can probably track down the owner who put it in. Plus it's nice to chit-chat with them to get a feel for how they treated and maintained the vehicle.

As for the tires, you may be able to get the tire manufacturer to warranty them if they're deteriotating already. Especially with so little mileage.
