My boyfriend just bought me a 75 coupe DeVille and I was wondering if you have any info on the car at all... care and repair, manuals, whatever. Mine hesitates after stopping too and you have to warm it up before taking off. But any other info would be fantastic. jrsbethany@hotmail.com.

Hesitation can be a problem on GM cars, my Pontiac Grand Prix would try to stall, especially when cold when you stand on the gas, a new accelerator pump on the carb sorted it, and improved drivebility.

"Get out of its way"-when it dies in turn lanes? More like you need to get it out of others' way!

"Huge and powerful"-well, it's huge, no doubt about that.

"1/4 mile in under 16 seconds"-hahahaha.

I've been driving a 1975 Sedan de Ville as my daily car for two years. I bought it as a toy, but then liked it so much I just drive it now. It is in very good original condition, and except for the cruise control it all works.

I've spent about $1700 in maintenance, and the performance and comfort are great, especially for a guy over 6' tall!

Sometimes I really miss driving a modern car, but I also enjoy taking care of this grand old lady from a by-gone era.

Too bad your "grand old lady" has a bit of a drinking problem, eh?

Dude, I'm 16 too! I just bought this car, with the 472ci. the one I got is gold, wth white top, and white/gold interior. I scored it on a deal from a guy who was gonna scrap it for a tax refund. he gave it to me for 200 bucks!

So do those large and ugly SUV's. Most people with classic Cadillacs don't drive them 10,000 or 20,000 miles per year, so fuel consumption doesn't really matter.

And there's a big difference driving a classic and stylish classic Cadillac than a modern box-like SUV.

You keep rocking your caddy. I am a 26 year old who rocks a 78 Lincoln Mark V and I love the looks I get. You got class man. I can dig it and to all of you who have hesitation at take off, try replacing the distributor. Also make sure if the car has points in the distributor (not sure when G.M. went to electronic distributors) to set your points correctly. That repair fixed my 73 Deville when I had it.

Drinking problem?

Let's do the math. Yes I get the same mileage as a full sized truck or SUV of modern make. But, most of those things cruising the roads have a payment along with the hefty gas bill. Not to mention the cost of registration and insurance. It cost me $12.00 (That's 12 one dollar bills) to register. $250.00 for a years worth of insurance. I think with all the money I save on the other incidentals I have money to spare on fuel. Plus, the ride is so choice.

A 7 litre engine is 427 cubic inches... may I ask what Cadillac of this era had this engine?

29th Oct 2020, 17:40

The commenter seems confused, which is understandable only being 16 and not a mechanic. The 65-70 Cadillac de Villes had 7L and 7.7L engines. By 1971, the 7L was gone.

29th Oct 2020, 17:43

Actually the Cadillac 7 litre was 429 CI and was used in the mid to late 1960s, then being replaced with the 472.

30th Oct 2020, 23:28

The downsized 1977 model also had a "7 litre", more commonly known as the 425 CID. The 16 year old said he had the same car... same as what? The late 60's models nor the post 1976 models were nothing close to the '75.

Registration renewal is very high in my state for a truck. Even a vanity tag is $80 year.

3rd Nov 2020, 20:43

Which state? It’s typically in the hundreds of dollars minimum even for older cars in the states I’ve lived in. Even if they let you slide on registration fees, they probably have high taxes somewhere else like property or state income tax or whatever to offset it, correct?

I bought a lot of premium fuel for my Cadillac. Like it was going out of style. But it was a GM

flagship. We took our Fleetwood in comfort and well rested at our destinations.

A vanity tag is above a registration renewal fee.

That engine family (472, 500, 425 and 368) were the last of the reliable Cadillac engines with big block size and iron block and head construction.

Yeah, the 368 in 1981 had the troublesome cylinder deactivation, but it was not the engine itself. Disconnecting the system resolved the hesitation problems.

After 1981 it was all downhill for actual "Cadillac" built engines; the 4100 was a nightmare. Between 1988-1995 you had the 4.5 and 4.9 which were actually pretty good, but still came from the 4100 design and require a lot of attention for cooling system maintenance. You have to religiously change the coolant and add the sealer tabs.

Then came the Northstar with way too many problems to even list, from faulty head bolts to constant oil leaks that were very expensive to fix.

It's too bad that CAFE regulations killed off the last of the Cadillac big block engines. If I had my choice, I would take a Fleetwood Brougham from 1986 - 1996 if you want a Cadillac with a solid engine, even though they had to resort to using Oldsmobile and Chevy V8s.
