The rear driver's side power door lock motor died and was replaced.

I've owned this car for nearly six months now, and I'm very impressed with its ride and handling considering its age. It had only 41,000 miles when I purchased it. The car was well-taken care of by its one previous owner.
I've only had to do routine maintenance work on the car, and the engine runs as smoothly as my 96 Town Car. The car is solid inside and out, and appears to be a well-manufactured luxury car. Ford definitely knows how to design and build their full-size cars for the long haul.
So far, it has been a wonderful second car and I feel safe driving it anywhere considering its above-average reliability and overall well-built design.
