Congratulations on your low mileage Eldorado! Dnt worry bout headgaskets. I've got a 95 Eldo with 250k miles on it now. I've had it over 15 years and had so much fun with it. Coast to coast and down to the French Quarter. No major failures and actually uses less oil now, than it ever did. Go figure. I've changed the oil when it said, usually about 6,800m, with Valvoline High Mileage and 2 qts Rislone. I loved blasting onto the interstates out west, where the speed limit is 85. Ran it up to 112 many times, where the fuel cuts off. Have fun with it. It's a fun, easy to drive, safe car. I put new bushings in the front and rear and struts, a long time ago in my yard. Interior is all ragged out now. I'll trade ya!
