Porsche:
Cayenne V6 and S – Numerous, in various colors
Cayenne Turbo – Black
Lamborghini Jalpa – Silver
Nissan/ACURA NSX – Red (featured in Autocar’s Sale pages a few years ago)
Subaru Impreza WRX Sti (pre-facelift 2002, with round lights) – Blue
Ford GT40 Mk1 (kit car)
Mercedes:
S500 – At least 2 in black, although I’ve seen more, potentially the same cars
S600 – Black
SL320 – Previous generation – Beige/gold, deep purple/maroon, silver with a kit
SL500 – New generation – Red
