I bought this CXL with the legendary 3.8 engine. It had 37,000 miles and was lightly used. I have driven it 7,000 miles. I love the 3.8 engine and GM got it right with the last of the series. Great around town mileage and good highway mileage. The original tires are about shot and I intend to upgrade with premium rubber. GM needs to put better original tires on its premium models. No problems and my mechanic has raved about the good deal I got from a VW dealer. The car depreciated to where a guy with two kids in college can afford a top line car for the cost of a tin can. My only complaint is that I wish the front leather seats were as nice as the European-style seats on my 1994 Bonneville.
I purchased this car used with 22,000 miles. Initially, I was very impressed with the design of the exterior and the interior materials. However, with time I have been mildly disappointed. No major complaints, just room for improvement. Like every other review, I am also disappointed with the fuel economy. Also, the 3.8 liter engine is not nearly as quiet or refined as other reviews suggest. The seats are unsupportive and stiff, although the leather is of very good quality. Have had an ongoing problem with the airbag light coming on for no apparent reason. Finally, the trunk lid has no handle to pull it up. Sounds minor but is very inconvenient.
The car is roomy and comfortable with great trunk space. Good quality leather - after almost 5 years still looks new. The only three problems are the low oil pressure warning comes on sometimes - taken to two different dealers who could find nothing wrong - hasn't caused any problems, goes off after a few seconds. The other issue is the clunking noise that comes from the steering column when I hit bumps. An the last issue is the A/C which I need to have checked because its unreliable - sometimes cold as the arctic going to warm as the desert back to cold as the arctic within a matter of minutes; however, when it does work, it's very cold :)
After having driven Japanese cars for almost 20 years, I purchased a GM car with trepidation. Amazingly, GM got it right with this car in 2005. When I turned in my Lexus in Aug '05 I felt deprived but the LaCrosse had all the luxury features and more!
