I must sell my gorgeous 1986 GN. located in SW Connecticut. I am thinking of running an ad in Hemmings classified but thought I would try the forum first. This is a great opportunity to buy an immaculate intercooled Grand National with all the best original options PLUS a huge basket of aftermarket goodies at a price substantially less than what it would cost to reproduce. Most of the work was performed under the guidance of the team at the Northeast GS/GN Club thanks to hours of help from John Csordas. I will be asking $67,000. If you are interested, let me know and we can talk about it. The finish is flawless, and it rides like a new car due to extensive chassis upgrades. Includes everything in the window sticker, except for electric antenna (replaced with new windshield with antenna built in as electric antennas inevitably fail) and body side molding which was removed during re-paint for a sleeker look. After the engine rebuild, dyno showed 343 HP and Torque at 396 at rear wheels. Very strong engine. I have Michigan Title document, which was signed over to me when I bought it, but Connecticut does not issue new titles for cars over 20 years old. The original title shows no liens.

This car was originally a Buick Executive Car (hence the expansive option list). After a year it was sold through a Detroit dealership to the first actual owner. It was driven for about ten years and then stored for the next twenty. I bought it in March 2016 (99,141 miles) from a man who bought it from that original owner but realized that the restoration would be too expensive for him. As you can read below, I performed a multi-year restoration including separating the body and frame.

Selling for health reasons. I need a walker to get around now and it’s just not practical to hold on to it. Typical “Little old MAN” driving it just on Sunday’s kind of use.

After talking with my experienced Buick guys at the Northeast GS/GN club, I came to the conclusion that I overestimated the correct market value of my car. I had originally listed it on Hemmings at $64,500 but I have since lowered that to $55,000. I figure this leaves me some room for the inevitable negotiation. I guess I was leaning too heavily on my investment amount (although I know that you never get that back). Anyway, I invite you all to look at my description above which is pretty comprehensive and also the link to the Hemmings ad so you can see all the pictures. If you are in the market for a 86/87 GN that you can count on, this is the one for you. Here are just some of the pictures.
