Purchased a used (4822 miles when I got the keys) 2004 manual tranny HCH. Tidbits fer ya to digest:

After 87 days of ownership: $130.62 spent on gas. 2979 miles driven. Average 34 miles per day. 4.3 cents per mile gas cost. Avg gas price paid with 6 fillups is $1.86. Avg MPG for my driven miles is 46.1 MPG, which is almost entirely City driving.

Trip B computer showed 34.4 as the "lifetime mpg" and I have since risen that to 37.8 with my "more intelligent" driving style.

Have noticed the peak performance on the realtime MPG meter when driving 37-42 MPH.
