Finally got her, 1999 Eldorado ESC, 105,109 miles. Thanks to all you guys (and gals) for this very informative forum. I really checked her out, no oil leaks, no transmission leaks. Drove her from Baltimore, Maryland to Dumfries, Virginia and back to be sure. Got a good on THANKS TO YOU GUYS.
Got her Carfax history, she's had all her maintenance done at Lindsey Cadillac, Alexander, Virginia.
She even has the original owner manual (with a cadillac ink pen....HA!)
