Are we all on the same page that a G35 is a Skyline? In Japan they're known as the Skyline G350. I'm not gonna say that they will equal the same amounts but they will be commonly seen once sales start picking up.
The G35 is a skyline...the G37 is probably still considered a skyline. The GT-R is not a skyline. Nissan is separating it out as a new platform with it's own code.
Stiff competition from cars like the 911, RS5, Z06 and M3 (to name a few) as well as the 70k price tag will keep this car somewhat rare. Also note, Nissan is not going to produce 40-50k of these a year...so don't expect to even see one for awhile.
Most of the kids that want one can't even afford an EVO or STi...in fact, most people can't afford a $70k car period...let alone the insurance on one. When the EVO first came to the states there was a huge buzz about it...I still don't see them everywhere and they cost half as much.
