Buick built the Special as its cheapest model for two decades, but the 322-cubic-inch V8 standard in 1956 still made it a genuine performer, not just an economy choice. The three chrome ventiports on each fender were Buicks own status code, telling buyers exactly where the Special sat below the four-port Super and Roadmaster. With 334,000 built across five body styles, it was anything but unpopular. It also represents one of the last years before the Special name disappeared entirely.
The Buick Special is the full sized entry level offering from 1936 until the end of 1958, when its replaced by the LeSabre. This 1956 version is powered by a 322 cu in (5.3 L) V8 engine putting out 250 HP.  The three vent ports located along the side of each fender, to the front of the doors show that this is a Special, with the more uptown models sporting four per side.]

Buick built the Special as its cheapest, shortest-wheelbase car for two decades, yet in 1956 it still came standard with a 322-cubic-inch V8 at a time when plenty of rivals were only just moving beyond six-cylinder power. The three chrome vent ports mounted low on each front fender are the giveaway that separates a Special from its costlier Buick siblings, since the more expensive models carried four ports per side rather than three, a detail Buick used instead of badging to signal trim level. Total Special production reached 334,000 units for the year, made across five body styles from convertible to station wagon, evidence that entry-level did not mean unpopular. What did buyers give up by choosing the cheapest Buick on the lot, and was it actually very much?
Buick’s Portholes Were a Status Symbol, Not Decoration
Buick introduced the ventiports, commonly called portholes, in 1949, and by the mid-1950s the count per fender had become an unofficial shorthand for trim level across the entire lineup: three ports signaled a Special, while the costlier Super and Roadmaster carried four. On this 1956 Special, the three-port fenders sit ahead of the front doors, a subtle detail that would have told any period buyer exactly how much they spent before ever looking at the badge.
The Cheapest Buick Was Still a Genuine V8
Every 1956 Buick, Special included, came standard with the 322-cubic-inch V8, and depending on carburetion and compression, output across the lineup ranged from roughly 220 horsepower on the base two-barrel Special engine up toward 255 on the four-barrel variants used in senior models, enough to push any 1956 Buick past 100 mph. Riding a 122-inch wheelbase and stretching 205 inches long, the Special traded some of the Roadmaster’s length and weight for a genuinely quicker, more affordable driving experience, backed by options like power steering, power brakes, and the optional Dynaflow automatic transmission.
The Last of a Generation
The Special nameplate had been running since 1936, and the 1956 model represented one of the final years before Buick’s entire lineup was reshaped for 1958, when the Special name would be dropped entirely and replaced by the LeSabre. A well-preserved 1956 Special, like the one pictured here in factory colors, represents the last full generation of Buick’s original entry-level formula before the brand moved further upmarket.
