I bought my 99 TL with 99K miles and couldn't have bought a better car. I have had all of the scheduled maintenance done on it at Firestone. No need to go to the dealership for any repairs. This week my catalytic converter is messed up and will have to be replaced. Firestone said that they are seeing a lot of those in a variety of makes and models because of the shift to ethanol. 152000 miles and one trip to the repair shop for something other than maintenance. The only complaint is that the auto day/night mirror is now tinted permanently on the bottom and not at all on the top. A little annoying.
Stereo, acceleration (and I owned a sports car before this car), reliability, heated seats, trunk space, gas mileage.
Cup holder size and placement, the trunk needs a keyhole for when my remote battery went dead, the rearview mirror. (these are all obviously things that aren't deal breakers)
