After enjoying my Buick for the last few years, and meeting (or re-meeting) a bunch of great folks along the way, it's time to sell my GN. With two little ones at home and a new (time-consuming) job, I don't have enough opportunity to take it out and have fun.

Asking $25,000. Lots of details below, pics coming.

Car drives beautifully and has a lot left in her. Hate to see it go, but it's just sitting in my garage right now. Still have the original turbo, intercooler, and powermaster unit too.

Beautiful car. Who built the motor? Factory crank? Was it turned? What’s the secondary gauge for? Paint looks immaculate. Has it been repainted and cleared?

Thanks, Jason

Previous owner (Dick Walker from Oklahoma) built the motor. Haven't spoken with him for a few years now, but he was well known in the midwest Buick community. Crank is factory, I don't believe it was turned.

Additional work (tuning, turbo, downpipe, alky, transmission, etc) was done by Anderson Performance in Maryland.

Console gages are water temperature & oil pressure. A-pillar gage is boost (I'll get a 2-pod holder and add the Scanmaster G up there soon). Under the hood is a fuel pressure gage.

It hasn't been repainted since I've owned it (2011), and I don't think it was repainted before then... but I could be mistaken. In school, I worked in a detail shop so I've tried to take care of the paint on this car as much as I can.

Hope this helps.

Thanks for your reply. Being from the Midwest the name sounds very familiar. I’m 90% sure I met him at a Buick vs. Ford race back in the mid 2000’s.

It is. I've got a few requests for better pics of the hail dings. I'll try to figure out a better way to see them and upload new pics. They're small and hard to photograph.
