Ok, basis for my thoughts were beetle with mendeola suspension or prepped 1303 suspension with big porsche brakes, adjustable shocks etc, fat tires, 5-speed transaxles, 2,5-3,0 litre engines N/A or turbo, modified aerodynamics and so on
Power to weigth ratio close to modern basic 911's, corvettes and older ferraris. With the same money you can build really nice beetle, if you have engineering skills and time..
But for someones it will not be beetle anymore if it has other engine and trans than t-1 based ones
I think its still beetle if it has original shape and same boxer 4-cylinder engine behind rear axle
But i prefer more "hich-tech" type 1 - type 4 - type 5 engines or strange dohc/ohc conversions more than subaru implants
"Hightech"=Nickies, state of the art heads, big cc, fuel injection, possible turbo etc.
