If you search on here in the FAQ section you should find something on common problems. I would say if you like the style of the car and the way it drives then go for it. Common problems that I know of are the waterpump and timing belt. I think all cars have problems with O2 sensors and PCV valves. There are some styling mods that can be done to the Contour if you have an intrest in that. I'm pretty happy with mine (listed in my sig) eventhough I've had a couple problems. If you go to
Car Domain you can see some mods and such that others have done to Contours. Many of these guys are CEG members and there are a few in Ontario I know, search the chapter forums there to find ones near you.
