Hi all- Thanks in advance for any help or advice from you more experienced folks. I am thinking of buying my father's 2006 Prius with 70k mileage. He lives in FL so no rough winter wear and tear. They just had the 70k check-up at the dealer and all looks good. They are the 2nd owners and all the service work (even from the 1st owner) has been done by their local Toyota dealer and thus all the records are accessible. My biggest worry is what I hear about the (larger of the two) batteries (there are two, yes?). Is 70k too risky a mileage? I know replacing the battery can cost a lot of money (I have read about 1500-2500) and I wonder how far past 100k do they last? Also, is the battery guaranteed until 100k on all Prius's? Can you get a new battery before 100k even if the battery is operating just fine!? Any advice, opinions, experience would be appreciated. I live in DC so it will be some effort to collect his car but I also feel 100% safe buying it from him (since I know him pretty well!) Thanks again.
