Hi,
My favorite years for the DeVille are 78 and 79. The cars run great and float like a Cadillac should.
The 425 engine has plenty of power to move this car. Just from the two pictures posted I can tell it has the opera lamp option which I always liked. I can also tell they replaced the rear fillers and didn't put back the little piece of trim that belongs on the lower side near the trunk. All in all a great looking car. I've seen low milage cars like this go from $5000 to $7000.

Im not much of an expert on the low miles cars.

Things I remember about that era from looking at / working on / owning several, even with the low miles most of this stuff could still be an issue just due to age:

Headliners usually came loose.

Something to do with the horn wiring in the steering column had issues in the cold which usually lead to all sorts of attempts to disable the horns which were not easily assessable.  The last one I owned had the wire and a couple that were not related to the horn cut.  Even at that I still had the battery die a few times just from the horn relay sticking on when it was cold.

The HVAC blower relay usually overheated and damaged the socket.  Again usually leading to poor hack repairs.

In the rear end the bolt that held the shaft for the spider gears is usually broke.  It breaks on the last thread so it can take some time to pick out.   It wont cause a problem with the regular operation of the car.  I have always run into it when replacing leaking rear axle seals.

Plastic cam timing gear (just like most of the 70's cars).

This is also the prime era for the charcoal canisters having issues which results in the little bits of charcoal getting sucked into the carb which causes all sorts of intermittent odd issues.

George
I bought my 78 , two years ago. I paid 15 grand for it. A lot of people say I paid to much, but I was offered 20 grand for it last Oct. It has most all the options Caddy could offer. Also has the level ride system. Mine had 11,500 miles on it.
 I have seen this one, because I track 78's that are for sale. I know what they are asking for it. It is nice ,but it doesnt have as many options on it ,as mine does.
 Ones that are loaded up to the max have been going for 12,000 to 20,000 dollars. That is if they are low low mileage cars.
This one probably would bring 8 to 10 thousand . I wish the guy had more pictures of it at his site.
 TJ is right. Head liners can be a problem, but it only cost me 40 bucks for material, and a few hours of my time to replace it. I have not had any problems with the drive train. I did go through and do a tune up and etc...to fix minor problems.
Now that all the problems are fixed , I have been enjoying the car. It is a nice handling car .
 Good luck to you.

This was the only problem I had inside the car. The headliner was perfect until I showed the car one hot summer day. It then started coming down.
 A few hours of work and it was replaced. Got the material from a local auto interior supply store.

I've seen that car on ebay a couple of times. From what I recall the seller is holding out for top dollar. I can't recall the figure but I vaguely remember there being a few minor issues with the car- I'd have to see it again.

Agreed 100% with Roy- there's not a prayer of getting a minty ultra-low mile 77-80 Cadillac Coupe deVille for $5,000-7,000 on the open market. The finest examples fetch in the mid teens all day long. Colors/color combination will also have a significant impact on values- darker colors having the edge with triple black being king in the marketplace. Options are also a factor but less so. A stripper triple black car will bring more than a loaded Seamist Green car any day.

In my humble opinion 77-80 Cadillacs are very undervalued (at present) for what they are and pristine, low mileage no-excuses examples in good colors are the way to go. The fact that the basic style of thses cars continued until the 1992 Brougham probably played a role in their slow start to collectibility status. Nevertheless they are one of the most bulletproof Cadillacs ever made and are a pleasure to operate under modern conditions and one of the simplest to service. 

I'd put this Autumn Haze Firemist example around $10-11K- assuming all is right with the car.

Here is the web site for the car.
It only has the bench seat, and the original floors mats are missing. With that low of mileage , it should have the mats.

http://www.everycarlisted.com/nh/portsmouth/cadillac/deville/vin-00006d47s8e675779

This would make me wonder what was done .
It shouldnt have had extensive restoration .

Agreed- I can't imagine what kind of restoration would've been needed on a 10,000 mile car of this vintage. I doubt this is the case but if it is, value would be affected. Floor mats were an option but the vast majority got them. Perhaps they're in trunk to preserve them??

There is a fella in Florida that paints the bottom of all the cars he sells black. The exhaust systems are painted silver. They look bad and he calls them original cars. Most of the time you can see the faded interiors on them. He dose a good clean up on them and pushes them out the door.
 He is on Ebay all the time.
 This is a picture of the bottom of my car. If you see a low mileage car, it should be rust free. Mine even had the original exhaust  system on it. No rust on the body at all.
That is where I would start if looking at a car. Also would check what options were on the car.

Thanks for the input.

This seller came down on his price some. Originally he had it listed for 20K now 15K. I was thinking 10-12 was about right.

I did notice the mats are not original and they should be for that amount of mileage. Also the bumper inserts do not match with the metal. I assume its age or they were replaced without someone matching the color fade of the metal due to age.

This car is about 50 miles from me so I could look at it. My issue is I am running out of garage space and may not be able to fit that into my garage.

The 1986-1991 Eldo's would fit though.

By the way nice coupe... amazing how just about every model GM sold when I was young came either in a coupe or sedan. Why would anyone not buy a coupe!

Sorry to all the sedan lovers!

I agree 10-12K; check undercarriage as well. Take someone with you if unsure how to discern original paint from refinished. RE: Bumper inserts- I assume you refer to body to bumper filler pieces- they're made of rubber and painted differently and seperately than sheetmetal therefore color variation on them is normal. Also normal for front fenders to differ slightly as they were painted seperately from the rest of the body.

1978 Coupe deVille is a far more serviceable than '89 Eldo- simpler w/o all the complex electronics and a much better investment overall. The last of the "real" Cadillacs. Agreed, 2 door is far preferable body style.

Maybe take a peek at this 1977 Coupe deVille. Appears to be a nice car. 1977 taillights are my favorite of the "tri-7s".

Too bad the top isn't Saffron like the body.

Not to bad. Car has a repaint. Pin stripe is wrong on fender extension. I wish when they put new fender extensions on ,that they would pop rivet the chrome pieces back on again. Everyone that sells these type of Caddy's seems to do this.
Hope is camera is off a little on the color on the inside.

Hmmm. I could find no definite indications of repaint. Only things I could see incorrect were hood ornament ('77 had see-through type used also on '76), the engine sticker missing from top of radiator support and pinstripe issue which often is due to either restriping done w/tape over old; striping w/ tape because car was ordered without; or striping went bad on extensions. Extensions may or may not have been replaced: On a '77 I once owned, one corner trim piece just came off when I was washing the car- the rubber having disintegrated there. I glued it back on. They were still the orig extensions. Can't tell what's the case here- I'd have better idea if I saw in person.

This car has the fact AM/FM CB radio.

I agree with others, 10k sounds fair and I would be willing to pay a couple thousand more if it was my ideal color.

Eric,
 Just my suspicions on the paint. There is more gloss to it on the outside of the car , than there is on the door edges ,and door sills. These areas should have more gloss to them. Interior parts have , to me , some sun fading. There is wear on the front drivers seat. Seat belt also didn't recline to store position.
Those rear fender extentions at the bottom run on an angle. The originals are straight across , and have a sharp edge.
 When people paint them they usually don't match. They also run the pin stripe straight out the back instead of the point on the end.
I would like to see some close ups of the paint, but I just feel it has been changed.
 Under the hood has definitely been painted. Engine and etc. Even the blue bolts have new paint.
I would have to see the car up close. Just my opinion.

This is from the link above in the car description

10k original miles in pristine condition. Extensive restoration with thousands invested and all receipts are available. The interior looks and smells new. Sit in the drivers seat, it's like stepping back in time. Close

So it seems to be inconsistent "original miles" but extensive restorations???  So I think your intuition on it not being original is most likely correct
