Great mileage, great quality, Toyota reputation, high-tech toy, and one other special reason. I own a micro-business that does on site tech-support. The Prius is a great advertisement...it's so recognizable as high-tech that I'm immediately recognizable as I pull up in front of your office, or even as I drive past WalMart.

Started a new job 50 miles away - commuting 100 miles/day (I certainly didn't buy my Prius for winter driving performance ).
I average 90 to 100 miles a day and I don't need to drive my big truck every day to/from work. I do need my truck on the weekends when I tow my Teryx to the trails, though.
I bought for reasons in this order: 1) Fuel Efficiency 2) Technologically Advanced/Features 3) Cargo Space for hauling those things that just don't fit in a trunk.
