Would you buy a NEW P3D if it had 2k miles on it? How many thousands discount would you expect off the price? Does it mean it's a demo car, or an older service loaner from this spring? I ask because there's a chance the tires are worn out, etc. Anything else to look for when picking it up? Would I have the right to expect the tires are replaced with new ones, since I heard the 20" performance tires are thin?
