I bought my 1996 Cadillac DeVille used in9/04. It had nearly 100,000 miles on it. I had problems right off with misfiring, which ended up being faulty plug wires (which had just been replaced??). I'm glad that I didn't have to pay for them! Also, the air conditioning didn't work. It took $200 to find a bad wire! Have put 20,000 miles on it since then without any major issues, which is a good thing because it costs a boat load to fix the thing! The previous owner burned 87 octane fuel and so have we-don't notice any performance difference even when we did try the expensive gasoline.
Inherited this vehicle from my in-laws and have spent the last few months getting in working order. Oil leaks that are cost-prohibitive to repair along with occasional over-heating (despite flushing of cooling system). Also, only about 10-12 MPG in city despite several fuel system treatments. Finally, electronic fuel display that jumps up and down several gallons within minutes.
love the engine but does use oil. drives like a sports car. Have replaced the middle arm rest twice in 6 years and needs it again. ac is slow to come on and still is on new models. Have slso replaced all 4 struts after 4 yrs-and that aint cheap!! love the rain sensor wipers .have owned this car 6 years and will probably get another new one soon but will miss the roomieness of the older models.
I purchased this vehicle with 26,600 miles in September 20009. Previous car was a 2004 Mitsubishi Galant. My particular example has had some issues. Two weeks after purchase, engine started misfiring but only at under 5 MPH. Replaced plugs, wires, etc. didn't fix it. At this point I've gotten used to it and don't want to put more money into it. Keyless entry stopped working for no reason. The car gets poor fuel economy (probably related to the misfire), around 10 in the city and 19 on the highway. Still, this is a very satisfying car to drive. Plenty of power and space for 5 adults (front center position is a squeeze). Trunk is immense.
