I changed my mind about starting small. Electra Meccanica s doing just that with their Solo EV commuter. They are planning to build around 1800 Solo's in 2016 for $19,888 Canadian ($15,000 US). If they can hand build an EV for $15K the Elio should handbuild for considerably less, say $10K and still affordable for the masses.
Starting smaller may in fact require less funding allowing time to get some Elio's on the road while creating some revenue flow. It may be doable, but not EMs plan.
building a few electric vehicles and a few gasoline powered vehicles is two very different things .... I have no clue how much a low numbered run of Elios would have to sell for but I doubt $10K would come close to buying the hand built power train
