Buick revamped its lineup for 1929, replacing the previous Standard and Master Sixes with three new series, designated the 116, 121, and 129 after their respective wheelbases, each extended an inch over its comparable predecessor. The first Buicks styled entirely by General Motor’s Art and Color Department, they were not without controversy. While trends of the time had body sides curving slightly inward from the beltline, these new Buicks featured just the opposite. A slight bulge along the beltline below the side windows earned them the pejorative “Pregnant Buicks.” The company revised the design the very next year.

Buick celebrated its 25th anniversary in 1929 to much marketing fanfare, offering a staggering 43 exterior paint options. Technical improvements to the models included a standard mechanical fuel pump, while closed models received dual electric windshield wipers and side cowl ventilators. The all-new chassis featured a thicker steel frame with more robust suspension components, including Lovejoy shock absorbers. Both of the available six-cylinder engines grew in displacement and power.

This Model 46 Business Coupe is one of only 4,339 produced for 1929, making it the second-rarest Series 121 body style offered that year. It benefits from a previous full rotisserie restoration in red and black with a tan interior. Though completed years ago, the quality of workmanship persists, thanks in no small part to the car having been well preserved within Sony Schwartz’s impressive collection. An accompanying plaque indicates the Buick received the Best of Auction Award at Kruse International’s 29th Annual Scottsdale Auction in January 2000.

Notable exterior features include cowl lights, a sun visor, a rear mounted spare tire, and impressively detailed wood-spoke wheels mounted with whitewall tires. The well-finished interior features pleasing tan upholstery with matching carpets and a lovely wood-rimmed steering wheel. Power comes from a 239-cubic-inch inline six-cylinder engine fed by a Marvel carburetor and operated through a three-speed manual transmission with floor shifter.

Innovative in their engineering and featuring a controversial one-year-only design, Buick’s 1929 models are highly compelling—all the more so when well preserved after being restored to a high standard as this handsome Business Coupe has been.
