My wife and I purchased a 2009 Prius a little more than a month ago (have almost 800 miles on it) and it is terrific. Currently averaging about 48-49 MPG with mostly city driving to/from work (about 2 miles one-way) as well as errands around town. Need to give it a bath and take some pictures now that the rain has seemingly come to an end here. She's a beauty, love the Blue Mica paint!
Glad you are enjoying your new '09 as much as I have enjoyed my '08. I put buying a Prius as one of my best purchases in my lifetime.
