The 1950 Buick has always been a “take-it-or-leave-it” kind of car, but Buick fans, especially fans of postwar models of the late 1940s and early 1950s, clearly love it. This Super Riviera (more on that in a minute) belonged to the seller’s grandmother, and it’s for sale on Facebook Marketplace in Heber, Arizona, with an asking price of $22,500.

Body tag from green 1950 Buick Super Sedan

The 125.5-inch wheelbase Super Riviera Sedan was a tremendously popular car: 114,745 were built with a base price of $2,212, making it the second most popular Buick in 1950 (behind the Model 41D Special Sedan). You may be wondering why the name “Riviera” is applied to this Super Sedan, and you have every right to be; Buick muddied the waters by calling their hardtops AND their extended-wheelbase sedans Rivieras. The Model 51 Super Sedan used the smaller B-Body with a 121.5-inch wheelbase (five inches shorter than the Riviera’s C-Body) and a different roofline.

Here’s how the trim tag of this Super breaks down:

  • Mod. No. 50-52: Super Riviera (called the Super 126 in the sales brochure)
  • Style No. 50-4519: 1950 is the model year, “4” stands for Buick, “5” stands for Super, and “19” is the Fisher Body code for a long-wheelbase sedan
  • Body No.: This is the Fisher sequence number, and “G” stands for Flint, Michigan, assembly
  • Trim No. 50: Gray Herringbone Cloth
  • Paint No. 25: Kashmir Green upper and lower

1950 Buick 263 engine

There are no pictures of the engine in the Marketplace ad, but there is a video of the engine running, and I captured this image from the video. Notice the “grand piano” hood, a feature Buick used until the 1953 models arrived.

In 1950, the Super had Buick’s new 263-cubic-inch straight-eight, while the Special carried over the old 248 for the last time. The 263 had quite a few detail improvements over the 248 (the head bolts were not open to water, for one), and it produced 128 horsepower with Dynaflow (124 with Synchromesh). Buick used a thinner steel shim head gasket for a higher compression ratio to gain the extra four horsepower. Also, Dynaflow cars such as this one had hydraulic lifters; in this system, oil was fed into the rocker shaft, through the rocker arms, down the pushrods, and into the lifters under low pressure (there is a metered fitting where the oil enters the head). Since Buick’s eight was not originally designed for hydraulics, there was no oil gallery to feed the lifters in the block.

Gray interior of 1950 Buick Super Sedan

The interior of most early 1950s cars was a bit drab, but there’s no getting over a Buick dashboard, and Supers had the huge centrally positioned speedometer in plain view of the driver. The seller says that the interior has been professionally restored, and the car has a new wiring harness. It does have the original version of the Dynaflow, which was used from 1948 (in Roadmasters only) to 1952. The Dynaflow was upgraded throughout the 1950s until its final year of 1963.

1950 Buick 6

Here’s where the Model 52 was really worth the extra money ($73 extra) over the Model 51: the generous rear seat. It’s no wonder that the Riviera outsold the standard sedan by more than two-to-one.

The seller of this Super says that it’s been repainted in its original Kashmir Green and has had some of its brightwork rechromed (a huge expense). It’s not a concours restoration, and it certainly needs a set of wide-whites (or blackwalls if you prefer), but it looks like a nice example of one of Buick’s most audacious cars ever, the controversial “Bucktooth” Buick. As the owner of a ’53 Buick myself, I know that values of mainstream early ’50s Buicks (non-Skylarks) are not terribly strong, so the $22,500 price tag might be ambitious (and it has been posted for four weeks) but not obnoxiously so. What is your opinion on the value of this refurbished Super?
