Here is a mini "retro" review of the kit contents, if anybody is interested...
First, AMT "Runabout":
The body (I don't know about the history of AMT and MPC, but I think the bodies in these kits are pretty much the same)
Interior tub and chassis (front suspension looks very Gremlin-esque)
Chrome tree - some nice options for a blown engine, drag wheels, etc (and stock wheels)
The V8, 429, and misc
The four cylinder, seats, tires
Box art
