I never understood the logic behind the Cadillac XLR. I mean, it had this great aggressive Art and Science design, but why would anyone buy it over the Corvette it was based on?

Not many people did. Cadillac unceremoniously killed the XLR off in 2009, and it has not been replaced. But if you did happen to buy an XLR, this one was the one to get: the XLR-V, with a supercharged Northstar V8 good for 443 horsepower.

John Davis and the MotorWeek crew tested the V roadster with some weird 12-bar blues music playing in the background, and found it to be pretty quick with a zero to 60 mph time of just 4.6 seconds and "firm and quick" handling.

Okay, it's good. But was it $100,000 good? I'm gonna go with "no" on that one.
