I'm in the market for a 3rd gen Prius. It seems like used 2011 are listed closer in price (sometimes more at my local dealer ) as a new 2012. However, 2010's are considerably less with several in the $15K to $20K range even with lower miles. Is this due to issues with the first year model, or does the Prius really drop that much in the third year as it comes off or is nearing the end of its warranty? I was considering a new 3 model, but picking up a used one with the depreciation hit already taken sounds enticing.
