I bought my '98 2.5 TL about 5 years ago, I also paid $1200 for the extended warranty to 100K miles. I never got to use the warranty. At 107K miles now, D4 light is out, and I have replaced both oxygen sensors as well as doing the scheduled 104K miles timing belt / water pump service. I also replaced the battery a couple years ago, and new brake pads. I'm due for replacing the AT fluid and filter. All in all, this car has been excellent. My car with 107K miles drives and feels like a new car - nothing loose or sloppy, and the throttle response is very smooth.
Great reliability, very comfortable and it drives wonderfully. Use the cruise control on the interstate, the car rides like 65 mph when you're actually cruising easily at 110 mph.
Poor fuel economy combined with the need for premium fuel are downers.
