re: the car with the VR6 motor, i've been told by someone who has been playing with these cars since release that the VR motor is heavy and throws off the balance of the car a bit. Depends on what your goals with the car are.

You do realise cars 1 and 2 aren't locally delivered (i.e. private imports from the UK)

I was going to suggest it might mean parts are harder to get but heck they're hard to get anyway :p
