You are saying that 370z is taken out of real competition since it doesn't come with a V8. But even in a straight line it can keep up with newest V8 mustangs, camaros, challengers (note that 2009 370z is much faster than 2009 mustangs, camaros, challengers but the new muscle cars have stepped up since then). The reason 370z is more expensive is because has superior handling and better quality interior.
