The Car Connection's Take
TCC Rating
8.6
8.4
TCC’s Bottom Line
The 2008 BMW 6-Series is overwrought and overstocked with technology that distracts even from the M6’s heroic performance. The eye-catching 2009 Cadillac XLR starts with the sharp-edged Corvette and makes some compromises for the sake of grand-touring luxury.
