Richard in the early 1990's had a 4.1 Buick stage 1 motor built for the car by Kenny Duttweiler backed by an Art Carr 2004R. Since my purchase of the car in 2011' I have completely gone though every component of the car top to bottom. Personally rebuilt the engine, transmission, rear end, suspension, brakes and all supporting mechanicals. Car currently shows somewhere around 47000 miles. Detailed every component, nut and bolt before installation. Rumor is the numbers match engine is still floating around in Maryland.

Some of the trim was painted gloss back, fender vents, front and window trim as well as the door trim is gloss black.

History documented by the GNX registry/ Doug Nigro. According to Doug this is one of a handful of GNX's with an ASC moon roof. Car is located in Kelowna BC, 2 hours north of the Oroville WA border, I will assist in transport to the USA and/or aligned with US transport to streamline the whole operation. $79000 USD and entertaining the idea of $59000 USD as a roller. Send me your favorite stock or modified 109'/2004R trans combo and I can install the drivetrain and prepare the car to your liking. I am also interested in a trade plus cash, clean low mile examples of 87 GN's, T-Type or Limited's either hardtop or CF5 interest in T-roof cars.
