  Ground breaking perfprmance - 2003 Cadillac Seville
  By dwayne13 - May 4 - 9:52 pm

  The 2003 Seville is a nice car with some great features and has that unique style as the price has drop and you can afford to have one. The North star motor can be a smooth surprise, but like with any vehicle you buy there is always some strength and weakness of any car, The car itself is a driving computer and if your not aware of this the car can be your worse nightmare in repair with sensors and the electronic hardware that runs the car, but aside of that the car is a marvel as the technology in the car has laid some ideas for the future Cadillacs, Its a true Cadillac and i just love mines with 96,000 miles and i am a mechanic if you see one for sale get one.

  03 STS - 2003 Cadillac Seville
  By Steven Jerome - August 5 - 12:07 pm

  This is my third STS and by far the best. I also had a 96 and a 98. This cars beautiful lines and aggressive wheels and tires make a great first impression. Mine has every option except navigation. It is very smooth, luxurious, and classy. Its much better than the Mercedes E430 that I traded in in every aspect. I am extremely satisfid with this car.

  LOVE It - 2003 Cadillac Seville
  By Matthew - July 31 - 1:45 am

  We had a 98 STS and loved it, but my partners brother wanted to buy it so we sold it to him. We just purchased an 03 STS about two weeks ago and love it. This one unlike our first one is loaded. It has a sunroof, navigation, back up sensors, and OnStar. We love this car. We will never get rid of it. Its got 34,000 miles on it and still has factory warranty. We had a new 2006 Mercedes R350, their new crossover vehicle. It was junk. They had to buy it back because they couldnt fix it. We also just bought one of the last new 06 Yukons. We had an 04 but sold it. This one also has nav, rear DVD, sunroof, Denali, and OnStar. We will stick with GM for life. Thanks for making such great cars.

  Fun to Drive - 2003 Cadillac Seville
  By Fred - March 30 - 9:07 pm

  We live in Montana, lots of open road. Great acceleration even on the hills. Corners well, fun to drive. Fuel economy is about 25 mpg over 2000 miles driven. Smooth shifting. Great gadgets, stereo is the best Ive ever had. Quiet ride even on bad roads. Handles very well in snow and ice.

  Bought Fathers Car and Love It - 2003 Cadillac Seville
  By MR. CADDY - January 22 - 5:05 am

  I bought my 2003 Cadillac Seville STS from my father. I previously had a Jeep Grand Cherokee Overland. It had more miles than his car, so I bought it and sold my Jeep to my sister. Her Jeep belonged to my mother first. I miss the all-wheel drive and the navigation but, the Caddy had less miles, and more warranty. Overall I am happy with the caddy, but miss my Jeep.

  Great SLS - 2003 Cadillac Seville
  By Raz - September 2 - 1:48 am

  Previously leased, low miles, 17k, clean, black with black leather, darkened the windows, came with chrome spoke wheels. Fine ride, very quick with 275hp, 26mpg highway, 22 in town. It is a little smooth compared to the STS but my 50 year old rear appreciates that! A real treat to look at and drive. :)

  Impressive Car - 2003 Cadillac Seville
  By Wonderful Car - February 18 - 11:39 am

  The 2003 Cadillac Seville SLS is a solid, well performing and handling luxury car in every respect. Its smooth, powerful V8 engine is a delight as is the smooth but controlled ride. It is a thrill every time you drive it. This car makes you feel special. I love the exterior styling, especially when compared to the new STS, which is bland and not distinctive. Its iInterior ergonomics are excellent and its design is great. The Seville SLS is a very comfortable car and a plesaure on a long trips. Also, its size is perfect, not too big and not too small. This is Cadillacs best car ever. It rides better than a Lexus LS400.

  My Second Cadillac - 2003 Cadillac Seville
  By CMS777 - November 11 - 4:42 pm

  Traded a 1999 Catera for my 2003 SLS. Enjoy it very much. Nice looking, drives like a dream. Not to firm yet not a yacht like a Deville. The interior is very nice. Driver control is excellent. I have a slight shake at highway speeds but will have the dealer check on first service. Considered CTS, glad I went with SLS. Used Cadillacs are in my opinion a very good value.

  Great Luxury Sedan - 2003 Cadillac Seville
  By Happy "Camper" - July 6 - 2:00 am

  Just the right size, rides as smooth as the DeVille, but doesnt look like a boat (smaller trunk is a negative). Great engine response--if yours doesnt MOVE OUT, try blowing out the carbon once/week. Pleasure to drive AND ride in, no squeeks/rattles @ 14K, small oil useage--1 qt/4K miles, very tolerable. Prefer FWD in Northern snowbelt, had to buy one of last SLSs with FWD.
