Wow.. this thread is ancient. But since we're here, I'll throw in a couple of cars:
JM: 1984(<-IIRC) Porsche 911 (lovely red G-model except for the ugly, factory-fitted spoiler), grey Ferrari F430 ("the idiot's Ferrari"), black Fiat Panda
RH: grey Range Rover (visible in S16 behind the scenes-video), Morgan AeroMax
JC: grey Overfinch/Holland&Holland Range Rover (presented as his in the same video ... empty gun-compartment, full booze-compartment)
