The Car Connection's Take
TCC Rating
7.6
8.0
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 BMW M5 has electrifying performance, but is saddled with an overdose of technology and a body in need of a few nips and tucks.
