With an average of 57,282 miles at 16 years old, MERCEDES 350 owners tend to use this car less than the typical driver. Very low mileage could mean the car has been garaged or used only for short trips, which can cause its own issues like battery drain and moisture buildup.

Buying a Used 2008 MERCEDES 350
At 16 years old, the MERCEDES 350 is firmly in budget territory. Purchase prices are low, but check for rust, worn suspension bushes, and electrical gremlins.
