"I have better mileage in a 2001 c320"4.0 starson by oludir
Pros: Great interior
Cons: Poor mileage from CNET review
Summary: I get 30mps on the freeway if I am careful and 25.9 if I really do not care. City mileage ranges from 19 to 23. This is on a 2001 C320. Why should a 2007 C300 have poorer gas mileage?
