LOL! Yeah, I posted something about that car a few months ago. It was a cool idea back in the day. Thing is, back in the day was 1978, and the new GTI with the 2.0 turbo, will trounce that 928-Rabbit.
Of course, the new GTI lists for about $30K.
Personally, I'd much rather have a regular 110 hp. Golf GTI with those great ATS wheels.
