S2000 for me. 04/05 for non drive by wire to be specific. If you want drive by wire, go with 08/09... or CR.
If you're going to stay in the streets 90% of the times (meaning very very little track time), I say go with 370Z. You'll be a much happier camper.
Can't beat the low end torque of the VQ with a 4 banger... haha
