i have a '88 300ZX, they are great cars but beware, their electronics are only good for about 10 to 12 years; that's the main problem because you'll have engine problems because of these electro sensors going bad, also check under the carpet, in the trunk area for rust. i've had no problems with t-top leaks.
mine is currently damage (minor accident) so it's not on the road but will be soon.
