My Taurus has 198k and it is still running strong. I only have minor problems with it. The engine is still strong, though I do need to replace the transmission gasket soon. I think with the amount of miles on the engine it should not be running this smoothly. The only things I've bought since I got it were the average things that you always have to fix on any car.
Trunk space because I can fit a huge infant stroller and a months worth of groceries in there at the same time, cruise on the wheel, and with road trips I don't have to keep stopping for gas.
The way the engine compartment was designed, it's hard to get to things like the belt without taking other stuff off.
