I know I've posted in response to other hybrid posts (including your earlier one, I believe), but I'll recap here: we now have 3 Prii in our family. Best car I've ever had, hands down. All are over 100k miles now, mine has 184k, all on original HV battery, no mechanical issues whatsoever. Tons of room in the back, you can put 8' lumber in and close the hatch, or a bike, or a table saw...
I just returned from helping my daughter move back to FL from Athens, GA -- drove 700 miles round trip with all of her possessions in the back of my car and towing a trailer, queen size bed strapped to the top. No, that's not recommended by Toyota, but it actually tows beautifully, if slowly.
My daughter's Prius got 53 mpg on the highway coming down here. Mine usually gets around 42, 45 and up if I drive more slowly on the highway. I paid $4900 for the oldest one (2004) with about 160k miles; $13k two years ago for a 2009 with ~65k miles. The only thing I've replaced on any of them is the low voltage battery (12v Optima battery, ~$130.)
