Admittedly biased, I can say the 370Z is an amazing car for the price. The Z has a fair amount more HP, but not a whole lot more torque. On the other hand, the weight advantage goes to the Megane (3000 vs. 3200). The Megane is FWD though, so I would either go with the Z or look at some of the other posters' suggestions. FWD on a car that looks that great is disappointing.
