Well guys, I just bought a Prius plug-in.
I went in for a Prius v, and didn't like it. The base model felt like a cheap minivan but squashed. It didn't suit my needs either. It turned out my daughter's car seat wouldn't even fit easily despite the overall car size being bigger, but it did fit in the regular Prius. I think the reason was the height of the seats. In the Prius it cleared the back edge of the seat, but in the Prius v it was right up against it. Both are less roomy in the rear seat than my old 2004 Prius, at least when it comes to child car seats if you can believe it.
So, I didn't even bother test driving the Prius v. I did test drive a base model Prius and liked it better. Eco mode sucks though. Normal mode is OK, but Power mode is better. The lack of door handle sensors on the passenger side and the trunk was annoying though.
But, it turns out what I wanted in a used Prius wasn't even available. He started talking about all their other cars but I wasn't interested. So, I was about to leave and the salesman was all stressed about losing a sale. He went to see if there were any other newly arrived ones available and their head guy suggested I have a look at their Prius plug-in demo, which wasn't actually listed for sale. (He probably figured that being an ex-Prius owner I might actually be stupid enough to buy it.

) I told them I didn't want a plug-in but I'd have a look anyway. The price listed in their system was also crazy high, so I'm guessing it was probably a price from a year or so back or something. Nonetheless I made an offer, and after some back and forth, it was accepted.
It's pricey for a used 2012 Prius, but OTOH it had only 29000 km and it was the top-of-the-line tricked out model with the radar cruise, collision warning stuff, higher end NAV system, door lock sensors on both sides and trunk, and all that various crap.
