I've run the M3 and was happy with it, but I'm partial to bimmer since I own a 1:1. The 200mm did seem to handle pretty good with it though. Right now I'm running the Infiniti G35 Coupe and it seems to handle well too. Both are better then the Porsche Carrera IMO. Local parking lot races are pretty lenient on what you can run so I'm not sure if any of those I've mentioned are actually legal or not.
