I bought this car almost 10 years ago used and I am very happy with the service life of this model car. This car is solid throughout. It looked great back then and it still does today. The finish on the car is still lustrous. The interior is also holding up. No crumbling of any kind like the Cadillacs of the past just normal wear and tear.
What made me buy this car was the ride. Excellent ride on all roads and best on the highway. Plenty of room for six and a gigantic trunk. My car has the 4.9L engine and it has 168,000 miles and everything still runs strong. Only thing relaced was the suspension/ball- joints and alternator.
I have been lucky as of so far with no major engine/trans problems. I have been keeping up with the maintenance on this car maybe thats why its lasted this long. One thing that is very expensive to replace is the suspension. I had a passive system put in from strut masters and the ride is Cadillac!
