Probably the same reason that all electric cars have terrible resale value except for the Tesla. They are practically obsolete once you drive them off the lot. Newer electric cars will keep offering better tech, batteries and driving range. Since I can't get a leased 500e in Canada, I would probably be happy to buy one for $5,000. But even at that price it would be a risk. No warranty service here in Canada (and presumably most states). And just getting one to you if the car isn't local would be either very costly or very time consuming.
