My roommate is on his second. He wrecked his first one. He's had it for 3 years I think. Only issue he's had is with his dash pod. The one that you can toggle between showing MPH, 0-60, etc. It's finally fixed, for now anyway.
A friend of mine has one and loves it, but he's never been able to get the alignment correct. Apparently a problem for some Z owners he's told me.
