Just bought a prius myself and love it. Mine is not the plug in model, its a prius two. 25,000 miles maintenance free so essentially 2 free oil changes and 5 tire rotations. I average 51 mpg right now. I have read everywhere trying to find tax credits, and the only thing I keep coming accross is a tax credit for all electric vehicles. The credit for Hybrids stopped a year or so ago.
