Wow, that’s astonishingly cheap. What’s wrong with these? How is the range? Can they drive at highway speeds?
They are cheap because they are similar in performance to other entry level economy cars, and the warranty for the battery is up. If the battery fails you’re in the ballpark of 6 or 7 thousand dollar repair.
The combination of information and parts available to fix Toyota NiMH packs is a big factor in why I own a vehicle with one :)
