Ooh.
Prolly a VW bug chassis, with all the pros and cons that come with it. IIRC there was an outfit that made a Bug-sized chassis that fit SBC's, so you could make it crazy fast if you could still find such a thing. Prolly easier/cheaper/simpler to just get a hotrod VW motor -- not like the thing is made to fit a radiator!
Many of the 70's kits were, let's say, highly dependent on the assembler for the end result... which is why you mostly see them being sold unfinished. They take a bazillion man hours, and require parts which were obscure 20-30 years ago, so even harder to find now. Expect to hone your fab skills in steel and fiberglass to complete such a thing, never mind the work to make the interior nice.
That one at least *looks* mostly all there, which is a plus. Pricing is an absolute crapshoot, since kits are so obscure.
What, like I've ever contemplated finding a Fiberfab Aztec 7?

I actually saw one local on CL a few years ago but had enough sense to stay away ... too many projects as it is.
