My wife and I are pretty much set on getting a Prius v 2 Clear Sky Metallic, there is one available in Fremont right now (oh no.. is someone going to snag it now that I posted this?? ). Anyway, I just wanted to make sure we are clear on the differences between the 2 and the 3 before we commit. I did quite a bit of research and it appears the only main difference is GPS and Entune/Voice Control, all of which do not warrant the $800 premium for the 3 IMO. But are there any other differences we may have overlooked and should consider? From the outside, the two look identical. Thanks!
