I bought this Car about 6 to 7 months ago when the gas prices were around $ 3.50 to 4 bucks a gallon. So not alot of people wanted this car because it doesnt get the best gas mileage. All I have owned is cadillacs, I love them. They don't hold there value well but you can pick them up at a good price if you really look around. I paid $7,000 total for mine with taxes. at the time its high book value was $11,500. The car does have a little over 100,000 miles but you can't tell by looking at it. For a big car that weighs alot this car will get up and fly, the ride is of course very comfortable. For the money you can't go wrong if you want a big, fast, and luxurious car, That is fun to drive.
The electronic speed omonter where everything is electronic including the gas gauge, tire pressure, MPG, oil life, E.T.C
The window regulator. Seems to have a problem in alot of cadillacs. Thats the only thing I can think of that GM built cheaply in this car.
