We solved the problem of adjusting the seat when we switch driving the Prius, his and hers. We found a good deal on 2010 a couple of days and my fiancee brought it home yesterday. Its basically a twin to mine, both the same year, color and both have window visors. Going to be different for her going from a Town & Country minivan to the Prius but she's happy with it so far. She already found out the Prius has less clearance in the front than she is used to.
Congratulations! My wife and I both got a 2013 Prius last month. Mine is a red and hers blue. She liked the red but didn't want the same color as mine. Since I bought mine a few days earlier I got first choice.
Growing up in a family with two identical Chevy Impalas, I suggest you put something on the car and the fobs to tell them apart or you'll have many frustrated trips back in the house to get the other fob.
