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.

TCC Likes

Supercar acceleration in the M6
Convertible option
Snug and cozy cockpit for two

Fast acceleration
Lusty V-8 engine sound
Nicely integrated keyless entry/starting

TCC Dislikes

Heavy, ponderous feel
Technology overload
Rear styling

Not as responsive as its looks suggest
Surprisingly small trunk
Less refined than it should be
