I have a 2000 Deville and love it. The crankshaft position sensors $300+, were a problem as soon as the warranty expired. Don't know why there wasn't a recall on them. Also have a problem with window regulators. They break and cost $287. This is a part that is poorly engineered. (Like the crank sensors)Lots of steel and a little plastic. The plastic breaks and the window quits working.
