I strongly recommend having a PPI (pre-purchase inspection) performed by a MB-trained tech so you have a professional evaluation of the car and know what expensive service items may be required immediately. A complete set of service records helps to determine if the car was serviced according to the MB service schedule. In my opinion it's best to buy a pre-owned MB from a MB dealer because the dealers sell CPO (certified pre-owned) vehicles.
