Ander Vilariño Facal (born 6 November 1979, Hondarribia) is a Spanish auto racing driver, who started in racing in 1996 in the Formula Renault Campus after having competed in some karting championships.
 He is son of former FIA European Hill Climb Champion (1989, 1990, 1991, 1992) and FIA European Hill Climb Championship Trophy Winner (2007) Andrés Vilariño.
Hispano-Suiza (English: Spanish-Swiss) was a Spanish automotive/engineering company and, after World War II, a French aviation engine and components manufacturer.
 It is best known for its luxury cars and aviation engines pre-World War II.
 In 1923, its French subsidiary became a semi-autonomous partnership with the Spanish parent company.
 In 1946, the Spanish parent company sold all its Spanish automotive assets to Enasa.
 In 1968, the French arm was taken over by the aerospace company Snecma, now a part of the French SAFRAN Group.
The Four Wheel Drive Auto Company, more often known as Four Wheel Drive (FWD), was a pioneering American company that developed and produced all-wheel drive vehicles.
 It was founded in 1909 in Clintonville, Wisconsin, as the Badger Four-Wheel Drive Auto Company by Otto Zachow and William Besserdich.
The Schützenpanzer Lang HS.30 (also "Schützenpanzer 12-3") was a West German infantry fighting vehicle developed from 1956 to 1958.
 It was a Swiss Hispano-Suiza design, with a Rolls-Royce engine.
 After some early mechanical problems only 2,176 were built of the 10,680 planned.
 It was armed with a 20 mm cannon which was an unusually powerful weapon for an armoured personnel carrier of the period.
 Its design proved to have many flaws and drawbacks and the construction was followed by a great political scandal in West Germany in the 1960s.
 2,176 SPz 12-3 and variants were built until 1962, for which the German government paid 517 million DM, or about 238,000 DM per vehicle.
 The SPz 12-3 first entered service with the "Panzergrenadier" battalions in 1960 and was replaced by the Marder infantry fighting vehicle from 1971.
The Griffin Auto Company Building is a historic automobile sales and service facility at 117 East Locust Street in El Dorado, Arkansas.
 It is a single story structure built out of reinforced concrete, with a full basement.
 The main floor housed the sales and showroom area, and the service area was in the basement.
 The building also includes a filling station area, which is the most decorative portion of the otherwise utilitarian structure.
 This area has pilastered columns that frame the automobile entry area, and the walls above the shelter entrance is decorated with bands of terra cotta and brick ornamentation.
 The Griffin Auto Company was established by three brothers from North Carolina, beginning as a livery stable business in 1899 before branching out into the new world of the automobile in 1915.
 They moved out of the building in 1960, since when it has been used by a variety of other sales-oriented businesses.
