(Also posted in Prius II main forum) Love the discussion here and learn a lot. I am in the market for a used prius and came across a 2009 prius on craigslist, which I test drove. I havent owned a prius before, but I loved the car overall. It is loaded with leather, nav, bluetooth etc. (I think it is with package #6). KBB costs it at about 19k. I have three questions: * The average mileage that this seller has gotten in 36 mpg, which was a huge surprise to me! Granted this is in SFO with hills, etc. but this seems to be a huge red flag to me. Any thoughts on whether this is a systemic issue with the vehicle vs just bad driving? * The car has about 45k miles, which is on the lower side. However other cars with much higher miles (70k to 110k) go for around 12 to 14k, and am curious why the price difference is so high with higher miles * There was a clapping sound when I braked hard, and slight rattling, should I be worried (is this indicative of a bigger problem)? Thanks in advance for all the insights and tips.
