I didn't know about it, but I have the old edition on my shelf. While I never played it, I did spend many an hour building cars for it. Honestly, I don't see much need to update the system, though maybe a little on the technological side (I mean: Early eighties car technology and tech-speculation vs 40 years of actual car-tech...).
Hmm.
I must ponder this. Maybe I WILL look into it after all..
