The Car Connection's Take

TCC’s Bottom Line
The 2009 Acura RL tops safety rankings and bristles with technology, but its detached driving feel and over-the-top front-end styling remove it from the best-in-class competition. The 2009 Cadillac STS isn’t a standout for looks, but you’ll appreciate the way it drives. The 2009 Infiniti M Series represents a compromise between sport and luxury—but a pleasant one that many shoppers should contemplate.
