I wish I could get your mileage, but obviously can't with my Prius II. The reason I bought it though was quite simple: I need to be able to fit more than 2 people, and also need to be able to fit a whole bunch of gear, and at times 2 bikes inside the car. I can do that with the Prius. Also, the Prius - though using more gas than the Insight - has the lowest emissions of any vehicle on the road (lower than the Insight), a diesel has much, much higher emissions. Finally, I really like the technology of the HSD. I do believe that it will evolve into cars that will break the 100 MPG barrier in the not too distant future.

The bottom line is though that all these full hybrids are great, all have their place, and we need more diversity and different styles of vehicles that are powerd by hybrid systems.

Cheers,
M
