This thread has taken a big OT turn, but I'll join in anyway.
The RX-8 is NOT a replacement for the RX-7. It's a completely different car aimed at a slightly different market, not to mention it is only a fraction of what a '95 RX-7 cost (not even considering inflation). I'd love one, especially since I have a small family now.
The Corvette is a 2 seater (as is the 350Z) and $15k more than it, so I don't even see why it is mentioned as an alternate vehicle. Trust me, I'd much rather a Corvette, but again only 2 seats. The G35 will come down to buyer preference is is very comparable IMHO.
I'd never buy an auto in such a low torque vehicle, but running through the gears at 9k RPM would definately be a blast with my 3 year old in the back seat.
I'd probably be pretty upset if it is over-rated, but if the performance numbers are correct (0-60, 1/4 mi), I'd get over it.
