Here in Portugal there are no Taurus, but Escorts and Mondeos. The '90 decade was desastrous for these models, rust and bad engines.
I believe Taurus can be a little better, and easy to find parts, also.
My experience with Volvo is fairly good. Have a 744 Turbo 2.0 '87 with 130k miles and didn't get any malfuncion except for the parts that the previous owner did not cared about: air conditioning, rad and water pump, belts, OD switch and electric terminals, starter, battery and generator. Those parts are naturally worn due to the ageing...
Besides that, engine runs perfectly, top comfort for family trips and no rust. It seems this car will never end, and I love it.
Parts are a bit expensive, but you can always find it in a scrapyard.
