Concerning the z31 (1984-89 300ZX) which is what I own:
Three z31 models were sold in the U.S.: 2 seater N.A. (Normal Aspiration), 2 + 2 N.A., and a 2 seater turbo.
The 2 + 2 has two doors and is about 10 inches longer than a 2 seater. The 2 rear seats can fold down. Just ask the seller which one of the three above models it is and donít go by any sedan or coupe description.
Concerning both the z31 and z32 models:
Tell the insurance agent that you havenít bought a z31/z32 yet and that want to know what the insurance premium would be if you do buy one. Shop around and compare it with what other insurance companies quote you for both the z31 and z32.
Insurance companies use many variables to calculate your insurance premium. Some of the variables can be controlled by you and others canít. The variables include: age of driver, no. of traffic violations over a certain time period, zip code of residence, no. of miles expected to be driven per year, other drivers that you allow to drive it, age of vehicle, type of vehicle (sports car, SUV, etc.), etc. Sports models like a z31/z32 command higher premiums and especially for males in your age category. The premium given to you can be the yearly amount or the biannual amount so be sure to ask which one it is.
Both the z31 and z32 are now in its old age. Rust, accidents, and owner neglect have taken their toll and the better preserved ones are going to command a higher selling price. Many OEM parts have been discontinued and harder to find. These cars can drive you right to the poor house if donít do your own repair and maintenance work. z31 models with a digital dash tend to have more electrical problems than models with an analog dash.
