Hello everyone. I just took ownership of this 99 Deville Concours. Its been in the family since new and belonged to my grandmother, then my dad and now me. It is far from what cars im used too ( mostly Mercedes and BMW's ) but my dad gave it to me as gift. From what I can tell it will need some suspension work and perhaps a tune up. Id like to bring it back to its original glory. So what better way than to join the experts. Looking forward bouncing off ideas.

Thank you! Grandma drove it to and from work as a nurse and never on road trips. Always kept it garaged and used rental cars for road trips lol. Then she retired and gave it to my dad who 3 years later gave it to me. It will need some love for sure. Especially that rear suspension.

Nice looking car. I'll guess that the ELC (Electronic Level Control) is faulty - the taildragger look. Either the (rear) shock bladders/air lines are leaking or the compressor/control head is seized.

Look under the spare tire cover - there should be a sticker with a bunch of codes on it. Is one code FE1 - soft springs/passive suspension, or FE3/F45 - sport springs/active suspension?

That has a direct bearing on advice offered.

How many miles on it?

Once you get it tuned up and get some fresh fluids, the consensus will likely recommend to exercise that engine by running it at wide open throttle aka WOT a few times to help clear out any built up carbon inside the engine.

Looks very clean. I like the color and the wheels & tires. I’m guessing the interior is also clean.

Thanks. I will replace ALL components that I think look brittle or are not functioning. I already pulled codes and you are correct the elc is definitely not working.

It has 98125 on it. The interior looks brand new lol with the exception of a sagging headliner. Kinda odd

That’s an average of about 4,500 miles per year... That’s pretty rare when you think about it. Sounds like it’s in good hands.

I bought my 2000 Deville DHS last year with 131,000 miles on it, which averages to 6,550 miles per year.



Cheers to keeping it clean for many years to come.

To say that she took care of this car is an understatement lol. Serviced at the dealer its entire life and then some. Yeah crazy to think she barely drove it. My dad only put 8k on it from the time he owned it.

I love the color of your car. Those are some sharp looking rims.

Thank you! And I also bought my car from the original owner.. Funny thing is I respectfully asked for as many receipts as possible but I think it turned into 1 of those situations where the person ends up shying away from providing the bulk of the information in fear of making the vehicle look bad... So all I got was a few oil change receipts and maybe a couple oddball repairs at the dealer.

I really wish I could’ve gotten everything, but I’m sure it wouldn’t have been anywhere near as extensive as your paperwork! Man keep that car around for another 20yrs. and who knows! Lol.

Nice Eldorado*. Yes, the ELC needs some TLC.

* Freudian slip ...............

I just recently installed a Monroe AK29 system with help from the forum. Works great and the ride is nicer as well.

===================
FE3 refers to stiffer springs and larger sway bars than the base model Deville -

F45 refers to the electronic struts and shocks -

you're going to cry when you find out how much replacement struts and shocks cost -
IF you can even find any -
