I drive almost 100 miles a day, and put on around 31K miles a year.
I also try to keep my cars for 10 years, and at that time I'll have well over 300K miles.

One main factor in my choosing HCH over Prius is that even if the battery goes completely flat at....let's say 250K miles I can still drive the car but with lower performance. I'm sure I can still get at least EPA without the hybrid battery.

Another factor was appearance.
Being an x-Dodge fan we drove to the Toyota dealer and was quickly shrugged off of the idea of a Prius and tried to be pushed into a Corolla. We didn't like the styling of the Corolla....and well frankly any Toyota we saw. They didn't have Prius on the lot and knew little about it.

But let me add that later I really like the unique styling of Prius as I see them occasionally on the road, and also the Insight.
I guess mainly because they break the "Egg" mold styling of many other cars.

I'm not saying that I made the wrong choice with my HCH, contrary I've been most pleased and have the best time driving it, even after 36,000 miles behind the wheels I still love it.

Efficient drivers do it better.
