RE: Just bought a car!
What engine? 1.8 turbo, 2.0 n/a, VR6?
They're decent cars, but replace your water pump/timing belt if it's the 2.0 or 1.8t if it hasn't been done. On your car it should be done every 60k miles. The water pump is driven by the timing belt, and when the water pump dies, you have to disassemble the t-belt/tensioner/etc to replace the water pump. It's not much extra for the water pump, and the plastic impeller on the OE part has a habit of disintegrating. If you have an overheating condition, that's the problem.
Anyway, the timing belt should be changed every 60,000 miles to prevent the timing belt from breaking. the 2.0 and 1.8t are interference engines, so if the belt breaks, your head will need to be rebuilt too, best case scenario.
They're good solid cars as long as the previous owner has taken care of it, just like any other car.
