The Car Connection's Take
TCC Rating
8.2
7.6
TCC’s Bottom Line
The 2007 Acura RL is a top-notch luxury sedan that’s sportier than its conservative exterior might indicate, yet those who want to be seen―or have a V-8 under the hood―should look elsewhere. The 2009 Cadillac STS isn’t a standout for looks, but you’ll appreciate the way it drives.
