I am glad you got good mileage with it. When they first came out we rented one and discovered for the type of driving we do on a daily basis it was not much better on mileage than a regular gas engine.
When we did the math (increased initial cost, increased interest payments etc) we were better off sticking with a gas engine. There also was an issue for us on space, with teens we need lots of leg room and trunk space for gear.
Our daily drive includes a mountain pass.
Dh recently drove from Calgary AB to Vancouver Island just under 700 miles on just over 13 US gallons of gas. A bit better than 50 miles to the US Gallon. Now it is basically downhill, I think he averaged 45 miles to the US gallon on the way up.
We have some friends who do most their driving locally and only need to worry about room for two adults who love their hybrid cars.
