The Car Connection's Take
TCC Rating
8.4
9.0
8.8
TCC’s Bottom Line
The 2009 Audi A8 and A8 L are nimble, refined luxury sedans that still stand out from the crowd. A less radical shape does wonders for the 2009 BMW 7-Series' appeal, though the dense layers of electronics require some patience and practice. The 2009 Mercedes-Benz S-Class is one of the best vehicles in the world—but you’ll pay for it.
