Its comfort, ease of use, security & performance are all at the peak of quality.

2005 Cadillac STS 4dr Sdn V6

Overall I absolutely Love It! The most useful feature of the car is the key fob. I can set it to unlock the drivers door only, the drivers & passenger door or do nothing as soon as the fob comes in close proximity to the car. I'm able to lock the doors from inside the house, a store, anywhere I remember I didn't lock them or just because I feel uneasy about something. It can be set for the horn to honk or not, the lights to come on & for how long or not. Each fob triggers its own settings for not only those options but all the seat, steering wheel, climate control & even radio station sets. Comfort & ease of use are covered very well but the engine performance is just as great. It's the V6 but it has no problem picking up speed in seconds & sounds good while doing it.

A safe, roomy car; deep trunk.

2005 Cadillac STS 4dr Sdn V8

It gets so-so gas mileage; 24 mph on the freeway. It has plenty of legroom; it has plenty of head room once you are in the car but have to stoop to get in it because of the slope. The side mirrors move whenever the door is opened and have to be readjusted which is dangerous. It has heated seats and air conditioning. The electronic gadgetry is hard to figure out but comes with a manual. It looks boxy but rides smooth. The seating is roomy. The trunk is not wide but it is deep. Over all, a good car.

My Cadillac of Cadillacs!

2005 Cadillac STS 4dr Sdn V6

The Cadillac sts is very reliable with its v6 Northstar engine. Leather seats with ultimate comfort. Heated seats as well as air conditioned seats. Heated steering wheel. Even in winter you'll warm up in second. This car has always been good on gas mileage. Also very reliable for long distance traveling. Drove it to Florida and back and was comfortable the whole drive. Rear wheel drive. Midnight blue color and black leather seats.
