Did Nissan ever iron out the front tire wear & alignment issues with the 350Z/G35 platform?
Fun cars to drive, well built, and look good... really good.
Don't know what tranny you are looking at, but the 6-speed sticks in the 350Z/G35 platform went through 9 revisions (I think it was 9, it was quite a few!) because of little issues. If you're buying the latest and greatest then this isn't a problem.
I almost bought a G35 Coupe last year but ended up taking home my Subaru STI. The G35 was just too "soft" for me.
