Got mine from JJ @ Gex. My mods so far include; Invisiglass, a pulley, a new car, pinball side mirrors, LEDs in the speakers, under the cab and soon in the buttons too.
Invisiglass was shipped safely with my game.

I attached a pulley to the ceiling to haul it upstairs. Why didn't I think of this sooner!

Found the gray one on eBay for $20. It looks just like my daily driver. Maisto and M2 both make 1:24 scale cars that bolt right into place.

Up close and with some white LEDs in place of the reds in back.

And some under cab that are tied to the speakers, both of which can change color or cycle or flash, etc.
