Hi all. My very first post in this forum

I'm interested in purchasing pretty and nicely used W203 wagon with around 30.000 miles (50.000 km) on the meter. Although I have some experience with the W203 sedan I have no experience with the W203 wagon. I may keep the car for 2 years. What will I need to look for, or be on outlook for, on this type of car? Can I expect a lot of maintenance needed in near future? What are the common failures ?

Thank you
