I get all the cars from work but they're basically new (no chipped paint or anything but out of packaging). Sometimes I get one or two for nothing and then other times I pay a couple of dollars for a bunch at once. He has heaps atm...well over 50 but I haven't counted them for a while, he has them all in a box that he drags around. He's good about putting them all away too
Most are crazy looking Hot Wheels with bright paint jobs, although I have got some nice traditional type Matchbox ones like Morris Mini van, old Ford van and stuff like that.
