That it has three row seating !.

The ride is smooth and the care handles excellent. . The gas mileage is great. . . So far the car has had no problems other than routine oil changes and a new set of tires.

LAFIEL S

Luxury. Good on gas. Has great acceleration. Easy to handle.

It is Smith riding. Great on gas. Very comfortably. The inside is nicely done. The hands free phone is great. I can set the drivers to suit me and my other half. Which is very helpful.

Diamond white paint looks silver and white. 18 speaker Bose system. Dual climate control temperature system. All power seats front driver and passenger with lumbar controls. The cruise control system works amazingly.

I have a Cadillac STS 2006 base model. I enjoy driving this very comfortable vehicle, it handles like a dream. I get excellent fuel mileage worth it, this vehicle is fully loaded, I enjoy the 18 speaker Bose system. Give me the best part of the car is the moonroof, I enjoy driving at night looking at the stars and the sites of the Skies. I have a V6 model it has more power than it is needed.

Katrina P

It is nice and cool and fun to drive and comfy. It is fast when I want it to be and can be very good vehicle in the snow as well it seems to get the job done when needing to. The car is red and has nice lights it never needs an oil change its always up to date it never has anything that is not up to date.

I like that you can put more than one CD, in the CD player.

Nothing at all is wrong with the car, I absolutely love it! Drives great, looks nice and very comfortable. Heated seats are a plus comes in handy very often. Also push start so makes things very easy. The buttons on the steering wheel comes in hands also.

It comes fully loaded and is a reliable car that is attractive and fun to drive.

I love my car - I do miss the old northstar engine that my old cars had. One great thing about my car is it came fully loaded with all the bells and whistles. It is a reliable stylish car that I enjoy driving.
