So how is everyone pleased with their Z performance wise?

Endgame

I have. I wanted a 350 sooo bad when they came out. I drove the ones with the rev up motor. The 350 was speedy, but the quality was subpar IMO. I happened to test drive an RX8 just because I was at a Mazda dealer getting my wife a CX7 and fell in love with the handling and feel of the RX8.

The 350's lack of handling prowess and subpar interior killed the 350 in my mind and I got the 8. The 370z is a completely different story. It is certainly faster than the 350, handles MUCH better, looks sexier, and has a much better build quality. My wife hated the 350 but loves the 370. I do think the 350's were stronger on the low end, but the 370 quickly catches us in the mid range, and then pull away quickly on the top end. It may just be my imagination, but the 370 revs much easier than the 350. The 350 does have a better sounding exhaust however...

If I had a 350, I would trade it in a heartbeat for a 370 (unless I had the Nismo 350; I love that car).
