This kind of set is one of the reasons I just find modern HotWheels to be .....
Why are they mixing cars from different eras, and what the **** is that van doing in the set? As for the graphics.
I think someone has mixed a wire wheel 'vette with a WhizzWheels top.
I remember this being in VolksWorld back in the 1990s. It also featured in the Vintage Volkswagen Club of America magazine. The car was still a shell back then.
There is thought to be only one of these left, but rumours suggest that maybe 10 or more were built.
A good video here
