2008 Cadillac sts is a smooth ride and gets great gas mileage.

To replace a headlight the entire front bumper and grill has to be removed also a tail light cannot be replaced the entire assembly has to be purchased at $1, 800 each also the service tire monitor light blinks constantly but the tire pressure is fine.

- Deborah R

It drives smooth and corners like it's on rails. It can stop on a dime and has no problems with changing altitude.

This car travel 1900 miles through the Colorado mountains and didn't miss a beat. It corners well, and drives smooth as silk. It has great acceleration and while it doesn't slam you back in your seat it would still be competitive with a sports car.

- anna c

It has rear backup security. When you get too close to something a alarm goes off. There is also a blinker alarm if you leave your blinker on for too long.

My car is lite colored and does not show dirt, it is comfortable to sit in and driving is a dream. I would like to get better gas mileage and the car has rust on the wheel wells and probably needs shocks or springs as it is not a smooth ride.
