Just researching the evolution of the T490, 492 and 497 sports racers.
Am I right in thinking that the cars are essentially the same - the 490 came first, and was then followed by an almost identical 492 model for S2000 racing and the 497 as a "winged" development of the 490. If this is correct, can anyone tell me:
1. The differences between the 490 an 492, if any, and
2. The differences between the 490 and 497 other than the wing.
Thanks - need it for an article I'm writing.
