I'm looking to buy a 2001 prius today and would like to know what kind of problems I can expect and what I need to look at to make sure the car is running good. I have driven 2007-2008 prius and love the ride but I am looking at the older 2001 prius right now. How much does it cost to replace the battery and is it more expensive to buy parts for these prius' along with higher repair costs? Can a general mechanic work out most issues with the prius? The car has under 100k miles on it right now. lastly have there been any recalls or any major things I should be concerned about. Thanks in advance!
