2007 Cadillac DTS-L – Brief: Over the past few years, several automakers have released stretched versions of their full-size sedans designed either for private individuals who prefer to be chauffeured in spacious comfort, or in the case of models like the 2007 Cadillac DTS-L, specifically for the high-end taxi services. There are stretched Jags and Lexus sedans, and with any trip to the airport you'll undoubtedly see countless elongated black Lincoln Town Cars, but not so many Cadillacs. Well, GM obviously wants its share of this lucrative pie, so the Cadillac DTS-L will provide these buyers, many who roll on countless miles and depend on these vehicles for their livelihood, an attractive new alternative.
