The $7500 is a tax credit, which assumes you have a tax liability of at least that - it would be much nicer if it were a rebate (as the states that offer one provide). Then, throw in the alternate minimum tax rules, and you may not get the full credit. It is NOT a rebate. Also, it's my understanding that the leasing company does not get that full amount...the way the law is written, they do not qualify for the full amount. A subsidized lease can be very good if, and only if, you want to swap the car out each time. It does not help if you then decide to buy the car, or if you purchase it and keep it for an extended period of time. On the i3 BEV, after the infant mortality issues are resolved, there is very little that should wear out, so maintenance should not be an issue unlike an ICE.
