    85 eldorado dilema... to buy or not ot buy

    ok guys, ive been back and forth so many times my head is spinning. i absolutly love the style of these eldos , but i am terrified reading about the HT100. i am looking for a clean eldo with low miles , and will be using it moderatly. i dont commute or anything , but will be using it as not only a sunday car. question is , if i take the proper measures... tune up / cat change / fluids / timing advance etc etc , can this motor survive without constantly worrying abotu it blowing up ? also , can any of you comment about how much you drive yours and how reliable its been? does it have enough power to handle itself on the highway / merging etc etc?

    thanks!

    The weak point is the engine. It couldn't pull a sick whore out of school and has trouble getting out of it's own way. I've had two and I can tell you if you go to pass, you'd better have LOTS of room. I have been half way through a pass and had to back down (very embarrassing for a Cadillac). Of the two I had, I had to replace the HG's on one. Other than that I loved the car.

    To give you another idea of just how underpowered it is, I have had it downshift at 60 MPH into a stiff headwind with the cruise on. Once back up to speed it would go back into OD, but being unable to maintain speed into the wind it would downshift again and this would continue. It was embarrassing.

    thats what i thought you would say. ive read that guys have installed high flow cats and advanced timing which woke up the engine considerably. i was hoping....

    you would be MUCH better off going a little newer -
    and looking at something with the 4.5 - or better yet - the 4.9 -

    OR - just leave it in the garage -
    and repete VROOM - VROOM - VROOM - while sitting behind the steering wheel -

    What about a '79-'81? Seems those would be a bit faster with the 350 or 368 (V8-6-4 disabled) not to mention the likelihood of being more reliable.

    If you are concerned about power find a nice 81. The 368 engine was cast iron. I've owned 2 84 Eldo's. They were my only car. The 1st one I installed the throttle body from an 81 and bumped the timing to 12 degrees. Great everyday car. The 2nd was high mileage (75,000) and was fine. Just change the coolant every 2 years, bump the timing and drive it! The 85 engine benefited by a better camshaft and improved intake gasket sealing. Just sold an 84 Sedan DeVille with 90,000 miles and it again was my only car. Timing bumped to 12 degrees and changed coolant every year. 2 months after selling the timing gear failed. He changed the gear and chain and is driving it every day as his only car. Arizona to California once a month. I'm not a fan of low mileage older cars. Low mileage usually means the PO only changed the oil and ignored the other fluids. Much rather buy a car with provable service history and higher mileage personally! Oil needs changed every 6 months regardless of mileage, coolant every year and brake fluid every two years whether its driven or not.

    ----------

    The 81 was really the best of the lot in my opinion. The only weak link was the climate controls. They tended to melt connectors and have faulty control heads. The 82 thru 85's had more reliable climate control. I would seek out an 81, modify the wiring on the variable displacement to be able to engage 4 cyl. mode once on the freeway. The 8-6-4 operation worked thru a simple one wire connection at the transmission. It would change from 8 to 6 to 4 once eng. temp was up and it saw 3rd gear. This wire can be cut and a toggle switch installed to manually engage 4 cyl mode at your whim.

    Correct me if I'm wrong carnut, but wasn't there two other choices in '81 (neither of which you want). Those being the V6 and the infamous diesel (I had one of those as well ).

    You are correct! The V/6 was a federal option I believe in 81 and Calif available in 82 only. Not a bad engine and it was the same size as the 4100. 4.1 liter Buick V/6.

    I would not hesitate to buy an 85 assuming it has provable service history. Because of the bad rap you should get it at a reasonable price. Great cruiser and timeless styling IMO!

    thats the first encouraging thing ive heard.... of course ive been fishing for something positive! you always want to hear what your looking to hear lol! agreed with the styling. im in love with these eldos , but want it to be a usable machine as well. i need it to function in the every day environment, meaning having charachteristics that can keep with todays traffin in the tristate nyc area. again , its not a commuter , but will be going into the city several times and being used... though not nearly as heavily as the typical "everyday driver" so is a 1908 considered as being in the "no buy zone" ?

    I had an 83 with the 4100.Ironically I never had a problem with the engine.It was everything else,AC,rear axle,power windows,antenae,hinges,rear end (axle).It all went,I was so annoyed I bought an 83 Lincoln town Car & never had a problem.
