The Lexus LS is a full-size luxury sedan that serves as the flagship model of Lexus, the luxury division of Toyota. Four generations of the sedan have been produced, all equipped with V8 engines and rear-wheel drive, although since 2006 all-wheel drive, hybrid, and long-wheelbase variants have also been offered. The original Lexus LS 400, the first Lexus to be developed, was introduced as the premium marque's debut model in September 1989. Subsequent redesigns included the second-generation LS 400 in November 1994, the LS 430 in January 2000, and the LS 460/LS 460 L series in 2006. A domestic-market version of the LS 400 and LS 430, badged as Toyota Celsior, was sold in Japan until the Lexus marque was introduced there in 2006. In 2006 (for the 2007 model year) the fourth-generation LS 460 debuted the first production eight-speed automatic transmission and an automatic parking system. In 2007, V8 hybrid powertrains were introduced on the LS 600h/LS 600h L sedans.

Development of the Lexus LS began in 1983 as the F1 project, the code name for a secret flagship sedan effort. The resulting sedan followed an extended five-year design process at a cost of over US$1 billion, and premiered with a new V8 engine and multiple luxury features. The Lexus LS was intended from its inception for export markets, and the Lexus division was formed to market and service the vehicle internationally. The original LS 400 debuted to strong sales, and was largely responsible for the successful launch of the Lexus marque. Each successive iteration of the vehicle has ranked as the best-selling flagship luxury sedan in the United States.

Carolla co-hosted the syndicated radio call-in program Loveline from 1995 to 2005 as well as the show's television incarnation on MTV from 1996 to 2000. He was the co-host and co-creator of the television program The Man Show (1999–2004), and the co-creator and a regular performer on the television show Crank Yankers (2002–2007).

Carolla was born in Los Angeles, California. His father, Jim Carolla, a psychologist of Italian heritage, and his mother, Kris (née Novello), who is of Hungarian descent, separated when Adam was young. Carolla was not given a middle name; on his driver's license application he filled the "middle name" blank with "Lakers" (after his love for the Los Angeles Lakers professional basketball team) and the made-up name still appears on his license.
