I loved the look and smooth ride. I bought my STS with 7K miles, certified pre-owned with extended warranty. At 18k miles the fuel pump went then 33K miles the water pump went after that it was something BIG each year. Cat converter replaced, intake position sensors, replaced vent solenoid, motor mounts, right & left lower control arms just to list a few. (seriously!) Transmission started clunking especially while driving slow or going from reverse to drive. Always garaged and maintained, I had to stop the $ bleeding at 85,000 miles when the transmission/drive train was about to drop out. The Cadillac dealer said new drive train $3,500 and there would be possible other issues. I'm done with Cadillac, this was my third, my beautiful Eldarado had mechanical troubles as well. Too bad, they were such beautiful LOOKING cars. Perhaps it is the aluminum North Star engine? Since my experience I have heard of others having numerous problems with this system.
Owned the 2000 STS, 2001 STS, 2002 STS, 2003 STS and now the 05 STS. The interior is shameful compared to the 98-04 STS. The exterior however is marvelous particular the front and back end. Lots of standard features love the power of the V8 N*. Heard the V6 was no good :(
In 2005 I leased my 5th (and final) one. I love the car. Comfortable, powerful and classy. But sad to say, Cadillac decided to discontinue the model. I have been driving these cars (SLS and STS)for over 15 years and never had any major problems. Except for normal wear of consumables. My 2005 has never had to be tuned, and continues to run like a dream. That's reliability.
AWESOME Bose 15 speaker sound system! Northstar V-8 power, heated/cooled seats, great looking leather & wood interior. Just a class car.
the ONLY negative is the lack of storage space. Glove compartment is insufficient, center console is small and any cd's use up most of the space.
I've always been a loyal Mercedes fan. Had a 500E which was my absolute favorite car. However, it was so unreliable and a fortune to repair. I decided to give a Seville a try, so I opted for a 2002 Seville SLS. I drove that for a few years and had no problems with it whatsoever. I was impressed with the Northstar engine and power, although it was a little soft and "grandpa" like for me. I saw a 2005 STS V8 and decided to test drive. I fell in love and purchased. It is much more sporty, handling more like a Mercedes than ever imagined. It is very comfortable, similar to Seville but not as soft, fast, a head- turner, reliable and oozes class! Not one problem so far. Absolutely love it!
Exterior styling, handling, fun to drive, nice interior and build quality, keyless ignition, lots of power when you need it.
More bass in stereo, Bose speakers sounds clear but need more bass. Improve fuel efficiency, that's about it.
I bought the STS because it fit our wants when shopping used cars: luxury, comfort, cheap. Poor resale value has worked just fine for us since we can buy a little more car for the money on the used market. Overall, I like the styling of the STS inside and out. Many prefer the CTS in both respects, but I prefer the toned-down design of the STS. I am not normally an extended warranty fan, but anybody considering the STS would be wise to find one under factory warranty, or in the case of a 2005 or 2006, a factory CPO warranty. Many little problems crop up. Take reviews here with a grain of salt. The 'high-end' stereo is NOT all that and is easily trumped by a decent aftermarket ones.
Exterior styling, smooth acceleration, wood accents, heated/cooled seats, no major failures.
Nearly useless Voice Recognition (VR), Nanny DVD, Nav and BT interface (cripples system when car is moving, hint: buy a kit and disable it), abysmal gas mileage, average seat comfort, relatively poor legroom in rear, many minor issues pop up
