Question About Future Buying (Nismo)

370zlove3

Seems like there is a lot of competition going on with the automakers.
First we have the V6 Mustang which now produces more HP, Chevy's Z28 Camaro, etc... I'm pretty sure Nissan has its radar on sight with them!

I have finally made my decision to wait until next winter to buy a 370Z - I'm probably going to opt for a Nismo but I'm aware of the competition.

I don't know my history with the 350Z but should I wait for next year to see if Nissan will drastically improve the 370Z and the Nismo in terms of performance?

Sure, we get a new color and some some cabin air filter and what not, but with the 350Z's history, will the 370Z get the same treatment in terms of performance? If I have to wait past next year's winter to go buy one, I will. And before anyone call me out on the performance comment, I mean stock specifications and not upgrading with Nissan's accessories aka catback exhaust.

One last question, this has nothing to do with the question above but rather the color. Which color requires the least amount of washing and cleaning to look good? And if you never waxed before or do not plan to, will it be okay?
