<P0-S0> seattle remained the corporate headquarters of boeing until 2001, when the company separated its headquarters from its major production facilities; the headquarters were moved to chicago. <P0-S1> the seattle area is still home to boeing's renton narrow-body plant (where the 707, 720, 727, and 757 were assembled, and the 737 is assembled today) and everett wide-body plant (assembly plant for the 747, 767, 777, and 787). <P0-S2> the company's credit union for employees, becu, remains based in the seattle area, though it is now open to all residents of washington. <SEP> <P1-S0> originally leased in 1759 to arthur guinness at ir £45 (irish pounds) per year for 9,000 years, st. james' gate has been the home of guinness ever since. <P1-S1> it became the largest brewery in ireland in 1838, and the largest in the world by 1886, with an annual output of 1.2 million barrels. <P1-S2> although no longer the largest brewery in the world, it is still the largest brewer of stout in the world. <P1-S3> the company has since bought out the originally leased property, and during the 19th and early 20th centuries the brewery owned most of the buildings in the surrounding area, including many streets of housing for brewery employees, and offices associated with the brewery. <P1-S4> the brewery also made all of its own power using its own power plant. <SEP> <P2-S0> It was sold in the U.S., Canada, and parts of China under Honda's luxury brand, Acura, from 1985 to 1995, as both a sedan, which was classified as a full-size car, and a coupe, which was classified as a mid-size car (similar to how the Honda Accord is set up today). <P2-S1> The Acura Legend is a mid-size luxury/executive car manufactured by Honda. <P2-S2> It was the first flagship sedan sold under the Acura nameplate, until being renamed in 1996 as the Acura 3.5RL. <P2-S3> The 3.5RL was the North American version of the KA9 series Honda Legend. <SEP> <P3-S0> A decade after the 1973 oil crisis, Honda, Toyota and Nissan, affected by the 1981 voluntary export restraints, opened US assembly plants and established their luxury divisions (Acura, Lexus and Infiniti, respectively) to distinguish themselves from their mass-market brands. <P3-S1> Some buyers lamented the small size of the first Japanese compacts, and both Toyota and Nissan (then known as Datsun) introduced larger cars such as the Toyota Corona Mark II, the Toyota Cressida, the Mazda 616 and Datsun 810, which added passenger space and amenities such as air conditioning, power steering, AM-FM radios, and even power windows and central locking without increasing the price of the vehicle. <SEP> <P4-S0> Rank Group Country Vehicles Toyota Japan 10,213,486 Volkswagen Group Germany 10,126,281 Hyundai South Korea 7,889,538 General Motors United States 7,793,066 5 Ford United States 6,429,485 6 Nissan Japan 5,556,241 7 Honda Japan 4,999,266 8 Fiat Chrysler Automobiles Italy / United States 4,681,457 9 Renault France 3,373,278 10 PSA France 3,152,787 11 Suzuki Japan 2,945,295 12 SAIC China 2,566,793 13 Daimler Germany 2,526,450 14 BMW Germany 2,359,756 15 Changan China 1,715,871
