That's the easy part to figure out. First, you supply a donor vehicle (minimum about $20k right now in a quick search). Next they remove the ice parts, which THEY KEEP (and presumably sell). That's probably $5k in parts or more. If they are buying in volume, the motors are probably no more expensive than the money they recoup for parts, so you are left with batteries, controllers, peripherals, and installation for $50k out of your pocket. Assuming they get a volume discount on batteries, too, they will make out well.I would like to know myself how they kept the price down under 50 thousand dollars.
At the end you will have paid over $70k. The Phoenix was supposed to run around $60k for fleets - this is right in line.
