I owned GNX #165 for several years when I lived in Florida and spent more money than I will ever admit modifying the car. It had the best paint job I had ever seen on a GN or GNX and was a daily driver for me.
Sorry many hate the concept but I am only going to live once and I drive every rare car I own to get enjoyment out of them. I raced that car in Bristol and locally at Bradenton. It ran 11.20's on drag radials.
Very finicky car though, it always seemed to need some adjustment. E-mail me at ekhanrahan@gmail.com if you want to talk more. I don't frequent this site.
