if it the red one it was spotted in pindi over a year back,.. it looked like an E/D-type hybrid but from a distance it was a convincing body.
@samhassn
jokes aside i wish you alot of luck, and i should point out that it CAN be done here if you have plenty of time and patience. it'll take a few tries on the same body to achieve what you want though and i suggest your initial die be a rough one so that the final touches are done by hand out of the die in case some muppet decides to copy it. my honest suggestion is to keep the dies to yourself when you are done with them otherwise within a few months you'll see ALOT of replicas of your car.
as far as engines are concerend i'd suggest any dual port VW engine (ideally a "AS" series engine) as a base and then you can bump it form 50hp to over the 115-150hp mark of the original "carrera" engine in the original 550 spyder with a whole bunch of go-fast parts. ifyou need help with specs and dimensions do let me know and i'll try my best to help you out.
Good luck
