The 2006 Cadillac Deville Professional is part of the eight-generation of this iconic luxury line and is based on the DTS platform. Its 32-valve V8 engine is paired with a 4-speed automatic transmission, delivering 275 horsepower for a potent blend of performance and smoothness. The Deville Professional is available only in one trim level but it includes features like OnStar communications, keyless entry, leather upholstery, and dual-zone automatic climate control for an upscale ride. Standard safety features include ABS and traction control, along with a host of airbags. This particular model boasts larger rear doors, designed for raised-roof limousine applications though maintaining a regular height profile itself. It's a unique take on luxury transportation that truly stands out in Cadillac's 2006 lineup.
