The left one is a popular Hot Wheels car with the hittle rack removed and some Epic 40k bits put in its place. (My kids call them hittles, not missles. If you say you are shooting your missles, they will miss.) The right car is stock except for the paintjob and a piece of card to cover a keyhole launcher in the back.
These are Hot Wheels motorcyles thar are actually in 1/64 scale, unlike the ones that come in the blister pack. I don't know alot about them because i got them from a thrift store. The rear tire was a magnet. I guess they went with some sort of stunt track. I took the magnet out because they kept sticking together.
Thanks for looking! Put your questions and comments in the box.
