My family bought an electric forklift for their factory in the early 90s. I think it is a Yale.
My sister has since taken over the forklift for her company and she has only replaced the batteries and the controller once.
These things are cheap to replace and not as much of a mystery as ICE engines.
I am seeing people replace old Prius hybrid batteries themselves with basic tools now.
I think the only thing I would be concern about is the crash safety for cars. Newer cars are safer. I think that would be the only draw to buy a newer vehicle.
