Pros: A tank goes a long way
Cons: odd design choices
I don' t actually own this Prius myself, but I drive my girlfriend's very regularly. While the acceleration leaves a bit to be desired, it's not bad, and that's not the point of the car. I certainly never feel like I'm in danger trying to merge on the freeway or anything.
When we've gone on longer trips, I'm always thrilled with the mileage. A tank lasts us forever. The odd design choices I refer to in the "Cons" are the weird bar across the back windshield, and also the shifting/parking process. I don't like that when you shift, it springs back to the central location, then if you want to park, it's push-button. What's wrong with the tried and true shift lever method?
Other than minor nits like that, I really do enjoy driving it. The eerie silence at stop lights is a cool reminder that you've stopped burning gas for a time, and it's also fun to watch the meter that shows energy being recouped to the battery during braking.
