Bought my 2.5TL in 2001 with 27k miles. Now at 145k miles and car still is doing fantastic! Service it every 30-45k miles and this car should run for a while. I have no complaints with this car and hope to get a new TL someday. Hopefully not for another 100,000 miles!
Reliability and overall quality. Has some minor issues that are common in the year/make/model, but nothing that has made me want or need to trade it in.
