The Car Connection's Take
TCC Rating
7.6
8.6
TCC’s Bottom Line
The STS is middle-of-the-pack in many respects, but it stands out as Cadillac’s technology flagship. The 2008 Audi A6 has plenty of competition, but its graceful look and feel set it apart from more brutal German and more clinical Japanese iron.
