Buick
In 1984, Buick was the official car of the XXIII Olympiad. A reorganization split manufacturing & engineering from sales and marketing. The first pilot Buick is produced at "Buick City", a state-of-the art assembly center built inside the walls of Buick's home plant at Flint. Buick had its best model year sales to date with 906,626 vehicles sold plus Buick worldwide sales topped one million for the first time. To close out 1984, Lloyd Reuss ended his tenure as general manager of the Buick Motor Division.
Buick Estate
The Buick Estate wagon was re-introduced as the top-level luxury station wagon for GM in 1970 to compete against the Mercury Colony Park and Chrysler Town & Country. 
Buick's first full-sized station wagon since 1964, it was available as a separate series on the B-body LeSabre and Wildcat, sharing their wheelbase, basic body and interior. The LeSabre Custom's bright rocker, wheelhouse and rear lower fender moldings were used. Woodgrain was an option for the body sides, incorporating the traditional "Sweepspear" feature. Interiors were all vinyl in a Custom grade. Despite being on the B-body it shared the C-body division flagship Electra's 455 cubic inch V8 and four VentiPorts on the front fenders. The following year the Estate would move up to Electra's larger body and more voluminous interior. 
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 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 front shoulder room and 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. And 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.
