Awesome on the GN! Please make sure you have an alarm system or some other anti-theft device on yours. I had an 86 and an 87. I had the 87 first and loved it but it was stolen within a few months of owning it. It was stolen less than 20ft from my bedroom window. I didn't even have a chance to fully hook up the NOS system. Parts from the car were on the market within a month. The 86 was nice but never really ran right.
Anyway, just wanted throw out the warning that these are a very commonly stolen car. Hope you enjoy yours!
