Didn't this chassis start in 2003.. and end about 2008? what are the years to avoid? What are the issues? I heard the brakes are expensive if they go out- is that common? Anything to watch for with the 320 engine? how about the 500? Does the 500 get decent fuel economy? Any 4matic issues? Does the 4matic get significantly worse mileage? Any downside to a 4matic?

I'd like to upgrade my wagon to a newer model and I'm not to keen on the w210 looks...
