His profile says he's in arizona though.
I'm obviously a little biased, but i'd stay with the zx, especially if you've already sunk time and money into it. If the 260 is rusty, its only going to be a big headache.
Yeah the zx is heavier, but for a street driven car its not the end of the world. It gets you both the timeless Z car look, some modern comforts, and still a hell of a performer with some mods.
Oh, and lets not forget t-tops. That gets girls, and if your lucky enough to own a 2+2, more than just one girl:icon44:
Not that I have anything against s30s, but if there's nothing wrong with the zx, why get rid of it?
