surely there is a Beetle base there?
Yes, that's a regular VW with a 'restyled' front.
Despite its appearance, it's not.
Well, if there's no VW in there it must be the prototype of General Motors' answer to the VW - a prototype Chevrolet Corvair (heavily disguised)
Not a prototype of any sort.
I meant it was not a mashup between a VW and any other car....even if the builder was inspired by a specific car.
Front-engined WV "kustom"?
Nope...just a different front end.
This was not a creation of a Mr Unknown from Nowhere...it's a name you pobably know and already featured here.
