We're really going off topic here, but why did you sell it looks mint? .
Wish I still had my first 240z. I sold it to a mate, who hasn't done much with it in the last 4 years as he has another early Z which he is fixing first. Then he had a child and other commitments. I am hoping to buy it back, at a marked up price from what I sold it to him and fix it up to original condition. Very original car and so much fun to drive, I really miss it.
My current Z isn't the same yet, funny how you get attached to your first car. I worked hard at 16-17 to buy it.
