Ma's 1990 Eldorado.. 82,000 miles, lived in the garage it's whole life, maintained to a "T". She didn't drive it, but my sis and I drove her around in it when we were in town. It was Pop's, and she maintained it for sentimental reasons, and maintained it well. So, no one wanted it after Ma passed away, so I took it over. This one has the 4.5 litre V-8, fuel injected, runs smoothly and is pretty quick, the interior and paint (Pearly-White) are perfect. It's clean as a whistle under the valve covers and passes emissions with flying colors. With the new brakes, suspension bushings, tires, alternator, starter, serpentine belt, and a host of other things that have been done to it the last three years, I figure it's worth keeping. Now, GM fans..is this one of the engines that had plastic intake manifolds/gaskets/parts that DexCool would have been an issue with? The radiator and cap and tank are clean as a whistle, but the system is charged with some form of Green, and the receipts show a Jiffy-Lube cooling system fluid exchange approximately three years ago. In 5 years' time, the car has only been driven a total of 4500 miles, and only 7K since pop died in 2001. I mean to use this car for my long hauls between Florida, New England, and No. Va. to save miles on my "new" Hyundai, which I've already racked up 23,000 miles on since August 2008. Anyone know anything about this era (1990) Cadillac I should look out for?
