I bought a Mercury Milan hybrid in November, so I went through the break-in period during the winter (mid-Michigan). Even so, my overall gas mileage was in the low 30's, and that's with the heat on and lots of short jaunts where the hybrid assist never even came on. Now that the weather has started to turn nice, my overall gas mileage has been in the mid 30's to low 40's. Lots of times, I don't even try to drive so as to maximize efficiency (horrors!), and I still get good mileage. I have no experience with the non-hybrid Milan/Fusion, so I can't compare it to the hybrid. However, my prior car was a 2004 I-4 Camrey, and my Milan has more pep, is more comfortable, and handles better on the snow that my old car did. My only complaints are (1) its hard to get in and out of (which is probably the same for the non-hybrid version as well), (2) the trunk is smaller (but it can still handle a couple of suitcases, and I haven't yet had to leave something becuase I couldn't pack it), and (3) the back seat doesn't fold down (a feature which I hardly ever used in my old car anyway). I love the rear view camera, nav screen and BLIS. If you can afford the premium for the hybrid, I highly recommend it.
