No Superstang buildups, but I have a Mach 1 and an Iron Horse..both built decades ago For reasons I can't recall, I decided the Mach i looked better in silver (probably because of a limited budget, and a can of silver paint sitting on the shelf). The tires were swapped with a set of low-profile big & littles from the scrap box (MPC Mako Shark maybe?). I've purchased two Mach 1's, and they both have the tall tires as found in the AMT Indy cars (Willard Battery Spl etc) in the box. I don't know what AMT was thinking, but they just don't fit the car at all.
I wish I had my box....got the kit when I was a kid and tossed the box; fortunately I saved the rest. In case anyone is wondering...here's the derby car. This one wears poor-quality copies of the original decals.
Here's the Gas Man, from the '60's-era 49er box. I don't know what the box will look like or the contents will be, but I know they have an original 49er kit on loan. Note that the 49er had unique custom wheels that they would have to re-tool if they were to bring it back.
Oh yea...I forgot about that horrible J Car! I had one too; my first IMC kit. It was scrapped for parts about an hour after I (sort of) built it. I recently bought another one; this time it will be done up right.
