Buick
The first two Buick automobiles were made in 1899 and 1900 at the "Buick Auto-Vim and Power Company" by chief-engineer Walter Marr, but company owner David Dunbar Buick was reluctant to begin making automobiles, being satisfied with stationary and marine engine production, so Marr left Buick in 1901 to found his own automobile company under his own name. His replacement was Eugene Richard, who applied for a patent in 1902 for Marr's valve-in-head (overhead valve) engine, which patent, number 771,095, was awarded to Richard in the name of Buick in 1904. In 1903, the third Buick automobile was made, this time by Richard, but in 1904 Buick, whose company was now called "Buick Motor Company," moved to Flint, Michigan, and Richard stayed behind. Marr was rehired in Flint as chief engineer, to begin making automobiles in production. That year, 37 Buick automobiles were made, production increasing to 750 in 1905, 1,400 in 1906, 4,641 in 1907, and 8,800 in 1908, taking the number one spot away from close competitors Oldsmobile, Ford, and Maxwell.
David Buick incorporated his company as the Buick Motor Company on May 19, 1903, in Detroit, Michigan. Buick had been financed by friend and fellow automobile enthusiast, Benjamin Briscoe, who sold control of the business to James H. Whiting (1842–1919), in September, 1903. of Flint Wagon Works, in Flint, Michigan. Whiting moved Buick to Flint that summer, to a location across the street from his factory, with the idea of adding Buick's engines to his wagons. David Buick stayed on as a manager, and re-hired Walter Marr as chief engineer. The engine Buick and Marr developed for this automobile was a two-cylinder valve-in-head engine of 159 cubic inches, with each cylinder horizontal and opposed to the other by 180 degrees. Whiting built only a few automobiles in 1904, by bringing Buick engines across the street where his workers shoehorned them into his wagons, before running out of capital, causing him to bring in William C. Durant that year as controlling investor. Durant spent the next four years turning Buick into the biggest-selling automobile brand in the US. Durant was co-owner, also in Flint, with Josiah Dallas Dort, of the Durant-Dort Carriage Company, which was the largest carriage-making company in the country and one of the largest in the world. Durant moved most production to the former Durant-Dort Imperial Wheel plant in Jackson, Michigan in 1905. Buick continued car production in Jackson through 1907, when Factory #1 was completed in Flint. The Jackson plant continued production with Buick trucks through 1912. David Buick sold his stock upon departure in 1906, and died in modest circumstances 25 years later. In 1907, Durant agreed to supply motors to R. S. McLaughlin in Canada, an auto maker, and in 1908 he founded General Motors.
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.
