Hi, I was wondering if there's a big difference between the 2nd Gen Prius years? I'm looking to buy a used Prius, hopefully under $15k within the next year. Should I be looking more at mileage? And how is Toyota financing? I've also been thinking about putting the $15k down on a 3rd Gen at a dealership, but my credit isn't good. What about the Prius C? I haven't seen one up close, are they that much smaller? I thank you all in advance for your advice.
