We are debating whether to bring couple of these ELF's to our store this summer. I happened to stumble on this neat video. A lot of good material about the history, production, challenges and benefits of this vehicle.
Yes that is the best Youtube video about the ELF but if you really search there are about 60 videos total. The price just increased twice recently, it is now $8899 base price but I think this is a pre-release strategy for the substantially upgraded ELF 2.0 with rear suspension, regenerative braking and reverse gear to be coming soon as an answer to the PEBL which has just started production.
