Plans Change: 1969 Buick GS 400 Convertible Project – Sold!
If you’re looking for a muscle car project capable of challenging both your money management and metalworking skills, this 1969 Buick GS400 convertible project listed on Craigslist in Amherst, New York (Buffalo) for $4,200 might just fit the bill. Reviewing the Hagerty Insurance Online Valuation Tool confirms this private seller has his GS400 priced well below the current #4 “Fair” (Daily Driver) estimate of $19,100. The private seller writes that “plans change” and that he’s only hoping to get out what he’s put into it.
The Gran Sport name has been used on several high-performance cars built by Buick since 1965. In the GM brand hierarchy, Buick was surpassed in luxury and comfort appointments only by Cadillac, which did not produce performance models. As a result, the Buick GS series was the most opulently equipped GM muscle cars of their era.
In 1968 and 1969 Buick offered the GS 400 in both a convertible and hardtop model. Standard GS 400 equipment was a Rochester Quadrajet topped 400 cubic inch V8 engine making 340 horsepower and 440 foot-pounds of torque, dual exhaust, 2.93 rear axle ratio, and the available three-speed turbo Super Turbine 400 automatic transmission. A 1968 or 1969 GS400 equipped with the TH400 auto transmission was faster off the line than many of its contemporaries thanks to an unusually “low” 1st gear. The factory air cleaner was covered with a large round chromed cover, secured with a wing nut. The small air scoop behind the hood hinge-line on the 1968 model was generally fake, although it could be functional if ordered with the very rare ram air package. 1969 brought ram air as standard to the GS.
Like all of the GM versions of this body style in this period, the convertible chassis was considerably more robust than the hardtop version. In fact, the convertible chassis was a full box frame chassis that had numerous lightening holes. The hardtop chassis was a 3/4 box frame with no lightening holes. All GS400 convertibles were built at GM’s Fremont, California assembly line.
The quirky YouTube Channel of OldCarMemories.com provides a thorough if a somewhat robotic overview of the ’68-’69 Buck GS series:
Seeing this Buick brings back memories of muscle car hunting in Western New York in the late seventies and early eighties. It was relatively easy to find otherwise complete cars removed from road duty as the heavily salted roads made these cars very rusty within a few years. Unlike back then, there is a wealth of quality replacement parts available to make the body repair a relatively straight forward process for any capable body shop. This example caught our eye as appearing to be a straight and most complete example although no underhood picture is provided. The only thing concerning us about this project is the odd block of wood appearing to be supporting something near the passenger door. As long as it’s not the frame, this car has a chance of recouping most of your investment once you complete the restoration. Good luck with the purchase!
Here’s the seller’s description:
“1969 Buick GS 400 Convertible. Numbers matchings motor and trans.
The motor is out of the car and apart. Missing the intake and carb.
The frame is very solid and the dash pad and bezel are in good shape.
The floor and trunk floor have rust. Both fenders have rust at the
bottom. The quarters are decent, but have some rust.
This is how I bought it. Plans change, I just want what I have in it,
not trying to make any money. I also have the build sheet.
This car is very restorable. Located in Amherst N.Y.
I won’t respond to (is this item still available) or blind offers.

Serious inquires only.
