1985 Cadillac DeVille Sedan from North America - Comments

The tape deck stopped working around 20,000 miles.

The electronic system (window switches, door locks) started to go at 30,000 miles.

The engine blew at 40,000 miles, had that replaced and the new engine started to go at 80,000 miles.

The HT4100 cannot support the weight of this car, therefore acceleration is sluggish.

The interior is extremely comfortable and luxurious and the ride is the best I have encountered.

The Sedan deVille is one of the niciest cars available and is a pleasure to drive (minus performance of course). Do not however buy this year of this car. The 1988 deVille ditches the HT4100 for another engine, and from what I hear is a much more reliable car.

I too had trouble with the ht4100 engine in my 1985 Sedan Deville. It went bad at 100k miles and I had it replaced since I don't like the looks of the 1990's Devilles. Sadly I sold my beloved 1985 Sedan Deville and kept my equally loved 1988 Coupe Deville when I moved and tenants were only allowed one car. I would give anything to have that car back in my driveway again and wish I sacrificed the nice apartment complex to keep my beloved "Black Chariot"

My first Cadillac Deville was a 1998 that I purchased in June of 2001. I liked the car so much and needed a second car, so I purchased a 1985 Cadillac Sedan Deville shortly after I bought the '98. When I first owned the '85, it was a great second car. I mean the car went anywhere I wanted it to go. Sadly my '98 Deville got stolen in the summer of 2002, and my '85 just flat out gave up on me (it being shared between the wife and I did not help matters much either} it had 100,000 miles on it when I purchased the '85 with only 20,000 on the new 4100 engine. 10,000 miles later, the radiator went bad and started leaking water and coolant into my smog pump, then leaked into the oil, which caused the engine to blow. I ended up getting rid of the 85. I now have a 2002 Cadillac Deville that I love.

I have an 84 deville, its been sitting in the garage and the engine hadnt been turned on for nearly 8 years with 104,000 miles on it. before it was stored it ran perfectly, no problems what so ever. I've been driving it around for nearly 3 months now with out a problem. Everything works perfect, engine tranny, brakes, eletronics etc. very sturdy car. When it came out of storage, I stuck a new battery in it and it sprung to life in about5 minutes.
