If you move out of CA/OR while leasing the Clarity EV, you have to turn it in and terminate the lease. You can actually do so any time with 90 days written notice. If we turn ours in after 2 years, we will have paid $85/mo all in (including license & registration) when factoring in the OR rebate. Keeping it 3 runs it up to about $145.
It is likely that lease extensions will be offered. they were on the Fit EV at a reduced price. We leased the Fit for almost 5 years, and they would have extended a 6th (but we wanted to move into a Clarity EV).
The Fit EV was unlimited miles, all maintenance (they even put new tires on when they wore out), plus comp & collision with zero deductible. It was insured as a Honda Fleet car and all we had to carry was liability.
