Astroroof Equipped: 1986 Buick Grand National

In the sea of seemingly endless Grand Nationals, you have to find ways to make your purchase stand out besides just claiming it’s the lowest mileage car available. Thankfully, this 1986 example does have two features running counter to the trends of most recent GN sales: it has high miles and it has a moonroof! Or, rather, an Astroroof, which makes it one of less than 198 cars ordered this way, according to the seller. Find it here on eBay with bidding over $13K.

As you might expect, that bid number means the reserve remains unmet, as these cars routinely bring higher offers than that, even in a market saturated with them. The seller notes the interior and exterior features are 100% original, but the drivetrain does sport some modifications (more on that later.) The paint does look clean and the body straight up and down the sides. This is a Washington State car since new with all manuals and original window sticker.

It sometimes gets challenging to find new ways to talk about a car we feature every few days. This Grand National helps solve that dilemma by being outfitted with the rare factory moonroof option, which isn’t so novel among the automotive industry at large, but it does seem like it was pretty rare across the Regal / Grand National lineup. The rest of the interior is standard GN fare, but it looks pretty decent for having 92,445 miles on the clock.

Speaking of the mileage, that’s a pretty lofty number for a car we’re accustomed to seeing kept in bubbles with less than 10K on the clock. Under hood is where we see some deviations from stock, with the seller disclosing mods including an upgraded fuel pump, injectors, fuel pressure regulator, exhaust, LT1 MAF, and a TT chip. Of course, it’s nothing super obvious, but some buyers may be turned off by the tweaks. Is this Astroroof-equipped GN a truly rare bird?

    As a lover of any Buick of the pre 70’s models, looking at this makes me want to heave. I would call it a “Bitsa.” Bitsa this and Bitsa that and whatever else I could find to cobble together this klunker. Yuch!

    Must be a good time to sell a GN? Seems like every day there’s one for sale on BF.

    As good as it got for a passenger car in the eighties, mods will only add to the excitement. Actually I’m happy to see one that was used as prescribed by Buick, not bought and stored away like a rare painting! Not too bad..

    I owned a ‘85 with the Astroroof. Good luck finding any of the Turbo models with them, you won’t. It was T Tops or hardtop. Was quite a car and literally beat the snot out of it and it took it. Broke a lot. But with any car, it’s repairable.
    The style of the G Body Buick’s were best in class of their day.

    The Electric Astro roof option is VERY RARE and desirable. It figures out to be 10 in every 1000 built with this option! How many are left!? lol

    We see lots of these here.

    Usually low mile ones that owners expect to command huge dollars. Not sure that happens.

    This is a higher miler for what we have seen. It will be interesting to see if reserve is reached.

      Lots of GN’s or the Astro roof option?
