I think the Schuppan 962CR has got to be the best looking "street" versions of the 962 - it was featured in the Victory By Design Porsche episode on Speed. Beautiful car.
Next to that is the Mclaren M6GT - that would have been my 2nd choice (maybe 1st?) after the Dino - I love the shape of that car. I think , because of it's early heritage it might make a better "road" car than the modern, highly purposeful designs. Still think the Dino would make a better road car, but as pointed out - RCR stands for...
The M8, another fabulous design - but in my mind it just doesn't come across right with a street legal windscreen (ala: Manta Mirage) - and especially with a roof - so maybe not a good road car design??
Considering the vintage era of most of the cars RCR offers, seems like a Mclaren would nicely round out the selection??
