Corroded sensor connections, this is common on these cars and will make them run bad. It is easy to fix, and makes a world of difference.
Dash was cracked, common on most vintage cars, but it has been replaced and looks great now.
The rubber suspension bushings are dried out and will need replacing to improve the cars handling, but it still handles very good with the old bushings.
Watch out for rust, try to find a Z car that has been kept in a garage and has not exposed to road salt.
These are awesome cars, they are very fast even as left as stock, but many upgrades are available to improve the handling and power. I don't think that there are many vintage cars that look better than a Z. I will leave my 280z stock and only replace what is worn from age. I absolutely love it!
Ah, yes, the 280Z 2+2.
Got mine just before graduate school. Had no money. Looking back, what I did was really kind of funny. Here's how to make a Z-car really move for almost no money, if your State allows it:
1. Lose the US-mandated front bumper (handling problems miraculously disappear).
2. Bolt on a $100 aluminum header and cheapo "turbo" muffler.
3. Disconnect and plug all smog & vacuum hoses surrounding the fuel-mixture gizmo, and adjust the single mixture screw until the exhaust is relatively clear.
4. Turn (advance) the distributer a few millimeters so the car runs on higher octane.
Can't tell you how many fancy Beemers I dusted. Ran it up to 120 mph in no time, but chickened out. Girlfriend sure hated the thing. Had to change girlfriends, of course.
I Purchased my 76 2+2 in 1983. Did 140 in it and never went over the speed limit again. Scared me and the girl with me to death. Just got another and am loving it again. It just seems older now.
