#46 of 50 1999 STS by darenw Sep 20, 2009 (3:43 pm)
HI, I AM LOOKING TO BUY A 99 STS THAT IS IN GREAT CONDITION, THE OWNER REPLACED THE NORTHSTAR MOTOR WITH ONE THAT HAD 20,000 MILES ON IT, 10,000 MILES AGO. IF I PURCHASE THIS CAR WHAT PRECAUTIONS SHOULD I DO TO IT TO PREVENT FUTURE HEAD GASKET PROBLEMS WITH THIS MOTOR. THE PRICE OF THE CAR IS 4,500 AND DRIVES GREAT.

#48 of 50 Get the STS by mourerj Sep 24, 2009 (11:22 pm)
Replying to: m4d_cow (Jul 12, 2008 9:54 pm) I've had my 2007 STS for nearly 3 years without a single problem. Statistical data suggests the person using the term "lemon" for his STS did indeed get a very rare bad apple of the bunch. Remeber Cadillac is #1 on several customer satisfaction surveys (e.g. JD power) -- yes, even beating #2 Lexus. Ditto for quality and repair frequency. Audi, BMW & MB have far more incidents per 1,000 cars sold than Cadillac does.   I find the powertrain on my car (320 hp V8 - 4WD), and frankly most of the car's features, superior to my last car, a 2005 Infiniti Q45. Even though the Q45's V8 had 20 more hp (340) and 18 more lb ft of torque (333 lb ft at 4000 rpm) than my STS, it was far from the sporty, fun to drive experience the STS provides. Actual 0-60 times are about 1.5 seconds better from the STS (5.7 sec), and their weights are nearly identical. Cadillac's sigma platform (CTS/STS) is far more rigid where it should be and is an entire cut above that in many of its competitors. The stereo (15 speakers, 5.1 sound, comes with Nav system) is the best I've ever heard in a car -- even trumping my uncle's $120,000 2008 MB CL550. For the price, you just can't beat the feature set and luxury + drive dynamics combo of the STS. Period. BTW. if you're looking at the 2008-2010 models, the V6 packs 302 hp with great low end torque -- according to several experts, it's so awesome that it renders the V8 a somewhat minor upgrade. GM's new High Feature V6s are the first from the Company that not only run head-to-head with the best from Japan and Europe, but in some respects is actually superior (fuel economy is not one of these respects -- so I read). The 2005-2007 V6 (255 hp/258 lb ft) is quick (7 sec 0-60) and far more than adequate. Its "numbers" are misleading, b/c the max hp and torque say far less about performance than many may think. GM's put some clever tech into the power transfer systems of these V6s. The V8 is better when you need a punch of power in the 45-75 mph range. Off the line the V8 is somewhat better, but not in a way that many drivers would likely even notice. Get the STS with Certified warranty. You'll have nearly the same time (6 years from new purchase or 100,000 miles) and coverage essentially identical to "bumper-to-bumper" with all of the "concierge" services like roadside assistance, new loaner cars to drive when yours is serviced and so on.

Replying to: cumptrnrd (Apr 30, 2006 4:51 pm) Just so you know, the Northstar V8 didn't hit showrooms until MY 1993. There is no '91 Northstar from GM. Also, the V8 used in the Lucerne is based on a 2000 update to the 300 hp (old SAE hp rules) version, with coil-on-plug ignition and roller follower valvegear for improved fuel economy and reduced emissions. Various undocumented "bug fixes" and tuning has been implemented every 2-3 years since 2000, making this one of the most tested & reliable V8s for the luxury market. Yes, it's a fairly old design, but one that is still world-class.   Sorry to hear about your Montana. I'm sure the reliability was terrible for that model and I don't blame you for never buying GM again, but I've had great experiences with them (albeit with a 2007 STS); non-GM affiliated quality studies prove that they've come an amazingly long way with quality, reliability and fit/finish, surpassing the Japanese makes in many cases.   The Toyota Matrix is the Toyota version of a joint venture between Toyota and General Motors, the GM part is the Pontiac Vibe. These cars were produced ont he same production line using the same quality standards & functional parts. Of course the badges & show surfaces were different. Many auto reviewers ranked the Matrix far superior to that of the Vibe (few direct comparisons, but when comparing their individual "final scores" and comments). We're all human with unavoidable biases, and this is working great for Toyota, but not so much for GM.

Replying to: kqqlv (Apr 12, 2009 6:25 am) Finally, someone who "gets it." That sounds arrogant, but the facts are clear. I'm a Biomechanical Engineer working for a tier-1 safety systems supplier and find it amazing how people can be so certain when drawing conclusions regarding matters with which they have little or no training/experience. The study showing how the Matrix/Vibe (GM/Toyota JV), coming off of the same line, received different scores when consumer (and even expert) reviewers wrote about both brands. It's no surprise the Vibe recieved far worse reviews than the identical Matrix. Most of these reviews were retracted or heavily modified subsequent to their authors learning of the pair's pedigree. Bias is unavoidable! Anyway, thanks for supplying some rational thought in this sea of ignorance and anecdotes disguised as facts.
