Overview & Reviews

Cadillac's full size sedan is all new for 2005, rounding out the luxury marque's self-proclaimed renaissance with a bevy of performance-oriented credentials, including rear-wheel drive and two powerful engine options. Cutting-edge styling, lavish interior appointments and available all-wheel drive have brought GM's flagship up to par with the best Europe and Japan have to offer.

• Full-size car at a midsize price, nimble road feel, powerful engine options, available all-wheel drive, optional Bose stereo is one of the best in its class.

• Sporty bucket seats might be a bit firm for some, plastic interior panels not quite up to German standards, only one transmission available.

  Reliable Beauty - 2005 Cadillac STS
  By Ed - November 28 - 2:00 am

  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. Thats reliability.

  Do not buy a Cadillac - 2005 Cadillac STS
  By jct - November 6 - 2:00 am

  We bought the car with 16,000 miles on it and right away we found out the car needed new tires and the wheels were way out of alignment and shortly after had a problem where it wouldnt start after filling it up with gas and had to get that fixed. at around 50,000 miles trans started to go out and finally went out at 77,000 miles and got that fixed. The same day we got the trans fixed the ac compressor froze up and it started spitting antifreeze out all over.

  My Second Favorite Car Ever - 2005 Cadillac STS
  By Tim - June 18 - 7:27 pm

  Ive 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!

  Great Car - 2005 Cadillac STS
  By JD - February 16 - 5:00 pm

  This is my first STS had a Toyota Avalon and really there is no comparison.This is so much more car in every respect, it is definitely not boring which is about the best thing I can say about the Avalon. I have the Northstar V8 it is fast. Love the interior except for the glove box.Nav works well and the AWD is great in snow and ice. I use the voice features to do almost everthing for me. I do not like the 2 different size tires. The fact that it is hard on tires is about my only complaint. Like all the bells and whistles more than you know you have.

  Florida STS Finds Happy Home in Canada - 2005 Cadillac STS
  By Roger Wyatt - February 4 - 6:40 pm

  I have been a Caddyman for a few years now and my first drive was a 1500 mile trip from Fort Lauderdale.The ride was not as soft as my 02 STS but was solid....this car can handle as it is equipped with the performance upgrade.The V6 sprints down the interstates with ease.The powerplant performs very well,transmission shifts are not noticeable at all.The interior is well laid out and being 6-4 and 270 I had no trouble in finding a comfortable driving position. The navigation system is easy to read with the big screen and the 5.1 stereo system is wonderful.I do notice a marginal difference in power from the 02 northstar V8 but the V6 had no trouble in performing a quick passing maneuver.

  cadillac reliability - 2005 Cadillac STS
  By harrison - November 7 - 10:26 am

  Bought this one certified used with 24,000 miles.. No issues at all in the entire vehicle history report this car stays on the road and not in the shop like previously owned BMWs and acuras.. You def can not get a better ride than with a caddy... Only issue not as quiet as a Lexus but theyre improving

  Amazing car! Good job Cadillac!! - 2005 Cadillac STS
  By CStradling24 - September 27 - 10:27 pm

  I am one of the biggest critics about everything. This car is nearly perfect. I am in my early 20s and usually people my age dont have cars like this. It was my dream car and met every expectation. I own the V8, fully loaded with absolute every feature besides AWD. It never gets old driving this car. When I bought it, the car was still under warranty and I had some small issues fixed without a problem. The performance of a car this heavy is nothing less than what you would expect from Cadillac. The interior looks great and very classy. I like how Cadillac did not go crazy with buttons, they kept it nice and simple.

  STS better than a BMW - 2005 Cadillac STS
  By Gordon Lewis - August 12 - 10:00 am

  Previuosly owned a BMW 528 sedan - Cadillac STS is by far as much if not more automobile for the buck & with just as much bang when it comes to handling, performance & comfort.

  The STS is a beautiful auto. It drives like a sedan but performs like a rocket. It is fast, sleek and a blast to drive. =0)
