370z is not loved (specially in TCL) mainly because of the badge. If it has a BMW badge, everyone here will hump it 24/7... example BMW 1M
only in TCL...
BMW 1M - 340hp, 3296lb, no one say it is a pig
BMW Z4M(E86) - 340hp, 3230, no one complaint about its weight
370z - 330-350hp, 3232lb, it is a pig
But i think the biggest 370z competition is probably this G37. G37 has a better badge, interior and rear seat... (not as hardcore) Yes, there is a $6000 different. But many people are willing to pay extra to "jump" especially most of them are financing or lease them. Also the Infiniti G probably have incentive (discount, financing or leasing deal) much more frequent than 370z.
