Tricky one this. I like the idea, but how long would it last ?
I remember back when i started almost 30 years ago, a couple of guys had Audi Quattro bodyshells on their Kyosho Scorpions that raced with the rest of the buggies. Looked great. But the phase didnt last long.
Then their was the Rallycross period in the 90's, which lasted all of about a year or two
I think you'd have to convert buggies though, rather than tourers... ?
I do have a brand new Parma Porsche 911 Carrera body shell, with full interior & spoiler that would good on a buggy though, subtly cut-down....
