the 2.0 is a reliable engine. The 4speed auto is usually reliable, but will benefit from a fluid change as although they are classed as "lifetime" fill, the fluid really should be changed anywhere over 100,000km.
Timing belts are every due every 100,000km. Make sure the water pump has been changed as the plastic impeller does break and the engine overheats. usually done when the timing belt is changed.
servicing costs will vary, but if you find a reputable mechanic who knows about these cars, the costs should not be too bad.
When you test drive one, check the heater!!! They are getting to the age where the cores can leak (My 2004 Bora did).
