We have had our C-Max SEL since May 2013 (Brand New) and Have Just Tripped 200,000 Miles Yesterday! Our Lifetime MPG is around 42, but do much better if I,m able to run about 5 MPH below Speed Limit. My wife drives it to work and usually drives it about 4 MPH over the Speed Limit. Since she drives it most of the time then she is the on effecting the MPG. Brake Score is 87 and our Regen Miles is well over 60.000 miles!
