I have a 1990 Deville 4.5L 4D sedan I picked up about a week ago, the car has been garaged most of its life and the mileage just rolled over 101,000. Before I picked up this car I know it had been sitting outside a garage for about 6-9 months, and was filled with bee's. Just before I picked up the car they replaced the distributor, spark plugs and plug wires, replaced the main gasket on the bottom of the transmission, changed the tranny oil, charged the battery, and topped off the other fluids. I have run a few oz of seafoam through the brake booster vacuum line to help clear out the cylinder
