Cadillac STS : Used
As Cadillac's luxury and performance flagship sedan, the handsome STS was available in its last generation from 2005 to 2011 inclusive. Bringing some all-American hospitality to the luxury sedan scene occupied heavily by German and Japanese forces like BMW, Mercedes-Benz and Lexus, it was available with 6- or 8-cylinder power and 2- or all-wheel drive.
