Accelleration-good, breaking, cornering probably not good (unless they are upgraded) That asking price seems kinda high, but I haven't seen it.
I miss my Z a lot, but I had many problems with it. I'd stick to my 240sx. In the future I plan on building a race 240Z which will be stripped down and SR20DET installed.

If you have your heart set on the car, try to talk down the price and drive it around. Check for leaks of course, and when driving around, sniff to see if you smell fumes. If you do, close the windows, blast the air/heater and it should go away. This means the rear hatch weather stipping needs to be replaced.
good luck, lemme know if you have any more Q's
