I don't have a Xbox but I am trying to talk a friend of mine who does in to getting "Grooverider - Slotcar Thunder". So far we have only found it via US sites & not in the UK. Apart from that I have a really basic PC game by Cool Dog called "Virtual Slot Racing" Its 4 cars with accellerate, boost & change lanes, on 2 lane circuit. & it includes a pitstop for fuel & tyres. Not bad as I picked it up at a car boot sale for 50 pence!
