To answer your question, my brother graduated from med school this spring and has been driving a worn out 86 bonneville for the past 15 years and is moving 600 miles from home for 5 yrs of residency and wanted something better. He bought the Jag from a distant relative. 02 45,000 miles, new rubber and the car looks mint, for $7000. Thought the deal was too good to pass up. Seems to be running great now.
As far as the towncar, any experience I have had with antifreeze in the crankcase is bad news. Had a 78 350 chevy drove I figure less than 20 miles with a blown head gasket and an 89 cutlass with 3.1 drove that 60 miles discovering I had antifreeze in the oil. Both engines had completely worn out bearings down to the babbit (copper/brass core) when disassemble, rods mains and cam. The cranks in both engines were fine however there was no engine knock. When I was finished fixing the engines, they were basicly new short blocks. New rings, bearings, cams, lifters, and oil pumps. No head work, and both engines are still on the road. One has 65k and the other around 80k. Bottom line is antifreeze is extremely hard on the bearings and oil pumps.
