I had an '04 HCH and it had 48.8 mpg when I traded in. The day I got my '06 I was convinced that it sucked. I have had it for 10 days now and have almost 700 miles on it. The Trip A meter I reset when I get gas and I never reset the B. The B is still pretty low 45.4 and the A is at 49.5 with 363 miles. I think that it has a lot to do with getting used to the car and seeing what changes you can make that will help. I also think the break in thing is true (and it is probably as much you as the car) as in my '04 it got significantly better after a few thousand miles.
