The Buick Estate was a line of full-sized station wagons manufactured by the Buick division of General Motors. As its premier luxury division, Cadillac, didn't offer a station wagon, the Estate was GM's most expensive and most fully equipped entry in the market.
Second generation (1971–1976)
The 1971 to 1976 Estates were the first Buick station wagons to be built on its largest chassis since the Roadmaster Estates of 1947–53. However, even though the Estate shared its 127.0-inch (3,230 mm) C-body wheelbase with the Electra 225, all 1971–76 GM wagons were assigned B-body-based per model numbers. The 1971–76 GM full-size bodies, at 64.3-inch (1,630 mm) front shoulder room and 63.4-inch (1,610 mm) rear shoulder room set a record for interior width that would not be matched by any car until the full-size GM rear-wheel drive models of the early to mid 1990s. The Estate also shared the Electra 225's interior and exterior styling from 1971 to 1974 (complete with the prerequisite four VentiPorts). Door trim and seats were not as plush in 1971–74 wagons and no door pull strap was included as it was on the Electra.
Although from 1975 to 1976 the number of VentiPorts were reduced by one, and the front fascia was downgraded to a LeSabre's (as was door trim and seats), the Electra 225 style chrome rocker panel moldings and distinctive Electra 225 style rear quarter panels (albeit without fender skirts) remained. The taillights were different from both the LeSabre and the Electra in all of these years. The Estate Wagons, as with other GM full-sized wagons during these years, used a rear suspension with multi-leaf springs instead of the coil springs used on other full-sized Buicks, and other full-sized GM cars.
The Estate Wagons also featured a new 'clamshell' tailgate design, marketed as the Glide-away Tailgate, where the rear power-operated glass slid up into the roof as the lower tailgate (manually or with power assist), slid into a recess under the cargo floor. Ultimately, the manual lower tailgate was supplanted by the power tailgate. The tailgate system was operated by switches on the instrument panel or a key switch on the rear quarter panel. Like a top-hinged tailgate, the clamshell design allowed a user to stand directly at the open cargo area without impediment, facilitating loading and unloading in tight spaces. the rear seat could be folded flat for additional cargo, and incorporated a 60/40 split so that extended cargo and passengers could be accommodated.
In its first year, 24,034 Estate Wagons were sold.
At 5,182 lb (2,351 kg) shipping weight, or about 5,400 lb (2,400 kg) curb weight, the three-seat 1974 Estate Wagons are easily the heaviest Buicks ever built, even heavier than the Buick Limited limousines of 1936–42. The 1975 and 1976 models were the longest station wagons ever built.
The Estate used the Buick 455 from 1971 to 1976 throughout. The last year that the Stage One high performance version, with high lift camshaft, enlarged ports, enlarged valves and dual exhaust was available was in 1974.
