That is a really nice car for someone to start with for the money, I just bought an almost identical condition 87 GN in Dec, with a few light mods and 92000 miles for $9300, the guy I bought it from wanted it GONE and needed the $ to put down on a new camaro, so I think I got it a little cheaper than a spring/ summer sale, he started at 10,500 and I picked it apart until we agreed on 9300, I started at 9k. but you car is a little more desireable being left alone, stereo, wheels stuff in the trunk and papers help it out, I would bet you wouldeasily get your money on EBAY if you have not tried it there, I have had great luck with cars and motorcycles there.
At this point not to desperate, i really like the car just dont like paying $160 a month in storage fees thats all. I do not have a garage for the car where i live and where i had it for free we lost the lease. U cannot keep a nice car like this outside. Wish me luck Thanks
