Bidding on a two separate 1950s American classics comes to a close today on Hemmings Auctions. First, a one-of-630 1957 Pontiac Bonneville with early fuel injection V-8 making more than 300 hp. Later, a 1950 Buick Special Tourback sedan hiding some suspension upgrades for daily driver use will sell to the highest bidder, as it has already met the reserve price.

Semon E. “Bunkie” Knudsen set out to change Pontiac’s image when he became head of the division in 1956. A first step was this dealer-special Bonneville convertible intended to lure in showroom shoppers with stunning looks and fuel injection feeding the 347 cu.in. V-8. Only 630 were produced, and far fewer survive today. This one on offer was restored before the current owner took possession in 2015 and is reported to still be in excellent condition. The engine is reported to run without problems, the Hydra-matic four-speed automatic shifts smooth. This rare piece of GM history is ready to drive into your garage.
While the Bonneville above is restored to factory condition, this Buick hides a few upgrades beneath the surface. You can’t tell at first glance but there’s an aftermarket four-link rear suspension with coilovers along with front disc brakes underneath the classic sheetmetal. There’s no LS swap under the hood as it retains the factory straight-8, reported to be original to the car. The transmission was upgraded to a Turbo Hydra-Matic 400 three speed, but the rest of the car retains the original look and feel of the height of postwar luxury.
