With soo many cars. you can't drive them all at the same time.
What are your plans for the Z? Do you just want it, just to want it?
Getting a base won't be a classic for a Z. You would want the Sport Touring with 19" fat wheels, illuminated kick plate, hand painted pin strip, window etching. Plus they are going to offer you all those extra options.
Unlimited Dent and Ding repair
Wheel and Tire coverage
Mechanical Protection + added warrenty
Skyway - gps tracker
So your going to have to take that into account if your going to put those extras on there.
S2k - Evo - Z what do you want to drive on the weekend? First thought, should be your choice to keep.
DON'T GET THE Z! I don't want you on the road
