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.

  Comfortable ride, good performance, clean styling - 2005 Cadillac STS
  By SLG - September 23 - 11:22 pm

  My 2005 STS Norstar V-8 since it was new. Currently it has almost 80,000 miles. There were a few minor mechanical problems when new, all covered under warranty, but over the last several years the repairs have been minimal, or just routine maintenance. The car has very good handling, braking and acceleration for a luxury car, and plenty of room to ride very comfortably, which makes road trips no problem. With the Norstar V-8 it has plenty of power, but without sounding like a "boy racer."

  Good and Bad :( - 2005 Cadillac STS
  By ahmaduhhs - October 23 - 4:24 pm

  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 :(

  Average - 2005 Cadillac STS
  By Slee - March 23 - 7:43 am

  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.

  awesome ultra fine classy car - 2005 Cadillac STS
  By ultrastark - May 30 - 2:32 am

  owning and especially driving this beauty are an absolute pleasure, yea there is the odd glitch here and there such as the interior shud be a bit more prestigous. the 320 hp is awesome they shud have made it a 360hp or so but the 320hp is superfine. sound system is beyond prestige. it handles like a sports car born on the track. what a sweet ride u built it right this time caddy, the headlight and light system mated to the front fascia is a designers showpiece.

  Cadillac: The American dream - 2005 Cadillac STS
  By Jason - February 20 - 6:56 pm

  Had this car for over a year now and it is the best car I have ever owned. AWD is good in the snow and great in the rain. Drives like a dream.

  Affordable muscle - 2005 Cadillac STS
  By Just Brilliant - February 3 - 9:51 am

  I keep a number of cars- for business, fun, performance and some just to look at. The STS is meant for business appts and really fits the category. Picking a client up in a $100k car or a $1k car sends a message. Its great for taking my hottie out on the town. No worries about the elements or parking lots. Dont settle for less then a fully optioned vehicle. Get the heads up display, V8, navi, sunroof, 15 speaker bose, adaptive cruise, 18 inch wheels. Reliability is an issue along with finding knowledgeable, competent and confident service.

  Superior exterior design - 2005 Cadillac STS
  By infinitetanner - November 6 - 2:57 pm

  This car has a stunning exterior design, and a nice cockpit layout. Its 4.6L 320 HP is responsive, however the transmission in the AWD has a delay- frustrating. Handles fantastic! Wont peel out though due to AWD system. I have the 1SG luxury edition, that offers: HID xenon head lamps, OnStar, XM, navigation with DVD player built in, 6cd changer, heated and a/c cooled front seats, heated rear seats, 18 rims, bluetooth hands free calling, one touch adjustable performance and touring suspention (formula 1 inspired), spoiler and much more! Despite being a tank, this car is small inside for rear passengers & front passenger. Glove box is a joke, trunk is decent-needs sunglassas holder badly!

  Good looks only! - 2005 Cadillac STS
  By 2005 STS - July 14 - 10:06 am

  Our car has been a lemon! Same tire thump as others reported & tires were replaced after about 4 trips to the dealer. Tires also after were replaced did not wear well or last long since can not be rotated. Power steering lines have been replaced. There was a burping noise coming from vents that was horrible as it sounded like someone was passing gas. Again after a few trips to dealer, some type of ventilation computer part was replaced. My car has been in the shop over a dozen times in 2 years. The problems were all "odd" and could not be diagnosed easily so there were many return trips. As other reviews have said when you buy a Cadillac you are not treated as if you buy a Lexus.
