I bought my 05 TL with a little over 54,000 miles. It now has 105,000 miles.
The 3rd generation TL's are very good cars. Comfortable, quiet, roomy, refined and I like the FWD because we do get snow here in KY. I just did the timing belt replacement (almost $1000 at dealer) so guess I will be keeping it for awhile.
I really like the TL as in my opinion gets great gas mileage for a car that performs this well. I average 22-24mpg combined and anywhere from 28-33mpg highway. The only complaints I have are the brakes. They perform well but rotors tend to warp easily and the calipers went bad around 95,000 miles.
Other than this the TL is probably the best car I have owned.
Nice stereo and really like the in dash 6-disc changer. HID headlights are wonderful.
Brakes and leather seats could be of better quality.
