A250 Suspension is really stiff for daily use.

Mercedes can be serviced outside, you don't have to worry about that, it should cost you less than RM500. In C&C or Hup Seng, it will be around Rm800-RM1000.

When it comes to conti, you always need to have some spare cash in case of major parts to be replaced. They are not cheap but they do last quite a while. Also, take note that newer Mercedes have many sensors now.
