Buick’s 1948 models remained largely the same as those offered in the two previous renditions of its post-war catalog. There was, quite simply, no reason to change: Buyers continued to bust down the doors at Buick dealers, and the design that had originally been created in 1942 (and had only been facelifted since) continued to appear striking and modern.

Despite its relatively static formula, the Roadmaster continued to draw in customers demanding new cars. In a climate of booming job creation and newfound success, Buicks found more owners than ever, with more 87,000 buyers motoring home in a new top-of-the-line Roadmaster in 1948. The series did, however, receive one notable update in the form of the new and optional Dynaflow automatic transmission.

This exterior of this 1948 Roadmaster Convertible is clad in the magnificent factory shade of Regency Blue Metallic to contrast with its red leather interior, a splendid improvement over the Cumulus Gray paint it wore when new. The resulting color combination is quite striking, especially when complemented by power-operated convertible top.

As one would expect of a top-of-the-line Buick in this ritzy era, the car is equipped with a power front bench seat (with later seatbelts for driver safety), power windows, power brakes, an AM radio, clock, heater, and carpeted floor mats. The Roadmaster provides a remarkably comfortable space in which to cruise about town thanks to these amenities, but also its supple suspension and favorable driving dynamics. The car’s chrome-ringed odometer presently indicates fewer than 60,100 miles at time of cataloguing.

The car is powered by its correct 320-cubic-inch Dynaflash straight-eight cylinder engine and the new-for-1948 Dynaflow automatic transmission. Perhaps due to its newness, the Dynaflow remained a particularly rare selection by new buyers; this particular Roadmaster surely benefits from enhanced collectability because of this feature. The car’s period-correct aesthetic is nicely rounded out by a set of color-matched factory hubs wrapped in wide whitewall tires, with the rear pair tucked behind a set of fender skirts.

This luxurious and wonderfully equipped 1948 Roadmaster Convertible now shows fewer than 60,100 actual miles at time of cataloguing. It is accompanied by an owner’s guide, Dynaflow instruction booklet, manual, spare wheel, jack, and two keys.
