One of them is supposed to be my Christmas present, but I haven't gotten around to opening it yet.
We were hoping to race against each other, but don't know if that'll work (thinking back to the old school days of kiddie R/C cars that would interfere with each other).
OK gang, here's the latest one we've acquired with it's aging mate. Hot Wheels Series 1 and 2 Mystery cars. Now that they are "loose" and out of the package, they lose value but who cares. Open to enjoy them.
