Congrats to you! I've had mine for about three months and I still say it to the car every time- I love you!
As for gas, I figured I cut my gas fillups in half and that's holding true. And I can now let the tank run down to under a 1/4 tank and STILL only pay 23 bucks for the fillup. My last car, I made a habit of filling up at just under half a tank. I considered the half way mark as my empty mark, and THAT was 25-30 bucks- every five days or so. Cutting gas in half figures right into the loan budget too. So far, the Fit has been an absolute champ. Enjoy yours!
