I have owned my Buick LaCrosse for ~10 years now, and it has been very reliable. It has a few mechanical issues that have needed to be addressed and some electrical issues, but overall, it has been the best car I have ever owned.

My last three vehicles have been Buicks. Overall, they are a very reliable, solid car with many extras that are actually standards for Buicks. They are a luxury car at a economic price. Buicks are on average good for over 150,000 miles. Some have over 200,000 miles on their Buicks.
