Sweet Spot of Late STS Models

Third Cadi! Traded up from Devilles which we loved for road cars. We drove both of those cars to nearly 200,000 miles. Altho the STS is somewhat smaller, it still delivers comfortably on road trips for my wife & me. Good gas mileage...mid-20s; great get up & go cruising or passing. Not the cushion ride cushion ride of the Devilles, but still steady, sure footed, & "inside conversation" quiet. AWD has performed nicely in wet or snow. Many more creature comforts than we had in either Deville. Liking it!

2005 Cadillac STS V-6 RWD Luxury Performance 1SC

I think the 2005 Cadillac STS with a 3.6L V-6 is a strong contender for best bargain-priced luxury car. I love this car. Without looking under the hood only the sharpest eye can pick out the difference between the V-6 and V-8. It has a very smooth, edgy, almost streamlined shape. With the V-6, I got everything I'd want in a luxury sport sedan, without an extravagantly high price of an import, and with the Luxury Performance package, it includes a lot of neat gadgetry (gorgeous wood trim including on the heated steering wheel, express up on all windows, NAV, rain-sensing wipers, etc). Of note, the keyless access and keyless engine start (all you need is the key fob) is awesome! With the key fob in your pocket, the car will unlock for you when you touch the handle. When you get inside, you put your foot on the brake pedal, push a button near the steering column, and the engine starts. When you park, you push the button to turn the engine off. When you close the last door and walk away from the car, it automatically locks itself. VERY slick! The only problem now is that I am spoiled and want every other car I drive to lock/unlock automatically now. LOL! The 3.6L V-6 variable valve timing (VVT) engine is a delightful, advanced engine. Think of it as a Northstar with 2 cylinders cut off. Power is smooth and the engine quiet, with plenty of power. It also has the huge advantage of being able to run well on regular gas. The V-6 puts out 255hp, but more importantly 252 lb-ft of torque (90% of which comes on at 1,600rpm they say). All this power gets to the rear wheels via a 5-speed, manually controllable, automatic transmission. Step on the gas and you go. The V-6 will pull the STS from 0 - 60mph in 6.6 seconds I read. This combo will serve perfectly well in 99% of the driving situations most of us are likely to find ourselves in. I thought I'd yearn for the '08 DI 303 hp version, or the V-8 Northstar, but I don't miss either. The V-6 also has the advantage of being lighter and more nimble that the V-8, especially with the performance package that adds stiffer suspension, bigger performance disc brakes, ZF steering, etc. My only concern with the V-6 engine is its fuel economy, in which I am getting about 18mpg in mixed city and highway driving. Its decent but not great in that respect. A used '05-'07 STS provides you with a quick, luxurious, feature-laden, and well built RWD sedan for the same money that you could get a brand new, mid-sized FWD family sedan for. However, you'll get better engineering, build quality, and more features. You'll be driving something with more panache and exclusivity, and showing pride in how domestic engineering can be on par with that of anything else in the world.

Great Car for its class

Great body style will turn heads, I have the pearl white great color, but Im not to thrilled about the color of my interior its tan and gets dirty very easliy get the V6 better on gas I average about 21 to 22mpg overall which is not bad, I know some people say that the trunk is not as big but Im here to say after driving for 8 hours with the xm radio, moonroof, comfortable seats, Bose system, and 4 people in the car 4 pieces of luggage bags of goodies and a small cooler, the trunk room was fine and car itself well just read again its all about a road trip in your Kitty Cat
