The good thing is that these cars look great in EVERY color, so no matter what you end up with you should be happy. I'd say the first thing you worry about would be the tranny, manual vs. auto is VERY different.
The second point is definitely don't rush to buy one, it took me over a year to get mine and I think it was well worth the wait. Finding yourself with buyer's remorse on a purchase over $30k is not a good thing.
Lastly... the Z WILL get you laid, so if you find yourself high 'n dry during this crisis, you should definitely pull the trigger!
