I have a 1984 300zx for sale. Has 120k miles, 5 speed, hardtop and was just inspected. Car is in excellent shape in and out needs nothing! New tires, brakes, and shocks. Car is beautiful no rust. A MUST SEE! Clean title. Have every reciept for every oil change and any work that has ever been done to it.
Good luck with the sale man, IDK if you have ever heard of some of the Z31 forums but try posting it up on them, im sure it would sell quick, people love slick tops. Plus thats a pretty solid price too, a lot of people try and get twice what these things are worth.
