I had one when I took mine in for the 90,000 checkup, and I was quite dissatisfied with the styling. The older Prius doesn’t look like a space ship. I felt cramped, and I had trouble seeing out the front and side easily. I also thought my head was too close to the ceiling.
It just didn’t feel comfortable like my current Prius. But it was cool though, with the economy/sports settings and the backup camera.
The over the shoulder visibility in the 2010 could be better. And the rear-view look takes some getting used to with the back window wiper.
