I bought a two tone blue on blue D'Elegance Coupe with an immaculate interior '84 back in 2000 for $700. Since then I've replace the engine with a GM 307cu.in. from a 1988 Sedan Deville (the 4100 had on 5 of the 8 cylinders working by then). I am pleased with the results, and I do prefer carburetor to fuel injection. I'm used to the 425 engine that comes in the 1977-79.
If you were to do an engine swap, I would suggest the 350 for a good amount of HP boost (I must admit I do like a bit of speed and power). The tranny is next; I'm trying to bring it back to showroom condition...

Hello.
I bought a 1984 Cadillac Sedan Deville about 3 years ago from a friend for $500. The car had been sitting in his yard for about 1 year not be driven and basically rusting away. Since then, I had the car painted, and I redid the whole interior. The only problems I have had is, I replaced the waterpump and the brakes, but that is normal on a 20 year old car! All the power windows still work, ac works OK for the most part. The gas is kind of sluggish, but I only drive 35 mph wherever I go:) I have had no problems with the 4100 or the transmission and the car rides so smooth. If you change the oil and keep up on the tune ups, the car will last a long time. They don't make them like this anymore for sure!
Thanks, Matt.

Whats up, I have an 84' coupe deville. its the most comfortable car I ever had, I have never had any problems with the motor. the only thing's I have ever changed were the battery and oxygen sensor. it also gets pretty good mileage for its size and weight 4000 pounds. 16/city 22/highway.

To the writer of the 3/22/2005 comment who said "The 4.9 V8 could run circles around the 4.1": No surprise there! Anything could run circles around the 4.1.

Since I was 10 years old I have also dreamed of having one of the early 80's Cadillacs, specifically the Deville or Fleetwood. There was one sitting in an older couples driveway for some time, 6 years to be exact. One day there was no licence plate so I went up to the door to as about it. I asked if it was for sale and it was. I knew I had to have it, this was my dream car and my first car. The couple had passed away and it had a new Northstar engine. He offered me to take it for $500, I could not believe it, the front was garaged all its life. It is not in bad condition. I will be driving it when it gets "tuned up". It is right now completely dead, but I cannot wait to drive it. It is very comfortable inside. I have not even owned it for two weeks and people are already asking me to sell it to them. I am only 17 and own my dream car.

I too, have a "1984 Coupe De Ville" with a 4100 engine{56,000 miles}. I think it's the best handling vehicle I've ever had! The only problem is the water pump. I have replaced two myself, along with two by Cadillac, that makes for five total in 56000 miles! OK, I'm done venting. There are seals (4) that need to be ordered from Cadillac, along with (2) gaskets if you are a do-it-yourselfer. Get your parts before starting this full day's project, and don't forget the bottle of Stop Leak. (I'm not kidding)!
Be cool on your stool, with your knees in the breeze!
