I am looking at a 2012 extremely clean all electric transit in my area. It has 11,000 miles on it. Runs well but my worries are that since the company went belly up who built the system. I won't be able to get parts for it. Some simple could wind up leaving me with a pile of scrap metal. I'm very interested in hearing anyone's thoughts on service and how long I can expect the vehicle''s battery's to last. Also, is there a replacement battery pack for them. Please advise. Thank you
