It's a matter of preference.
It's a matter of preference. My boy has a 370Z and I have a Camaro SS. Granted it's not an even match as the Camaro has a Supercharged LS7 Engine that is tuned for 636 HP (daily driver gets 4 mpg). Two very different cars; The Nissan is light and quick but the heavier Camaro delivers a much smoother ride and top end. The Nissan aftermarket upgrades to money ratio is much lower ($10K) gets you 500 hp+ with the Nissan. The Camaro has over $135K in parts and labor into it. If the goal is fast 1/4 mile races the Nissan is the way to go. If you are looking for 200 mph top end, however, the Nissan will never hit those numbers. It would make sense to grab a 370Z over a V6 Camaro or other muscle car any day but if you are looking for supercar performance a V8 Camaro capable of pushing over 900 HP on the track is the way to go. Both are fun cars to drive but are very different in handling, speed and general purpose; In my opinion you can't pin the two against each other.
