NO CLUE what I will do in the next 36months. I leased My12 SL a few months ago. 39months @ 15kper year. Residual value/balloon payment being $17k. I did have some negative equity on my trade but with the 7500 and another 500 rebate it sucked up the negative...completely.
Currently drive 68miles RT, the winter doesnt help So wife is the primary LEAF driver in winter until it warms up (she does all city 15-20miles per day), and I drive our Pathfinder. With possibly moving next year to a shorter 14mile (28mile RT) commute Ill love being able to go to and from work with additional range, unlike now.
I'll plan on turning my lease in if the car's value drops significantly or there is any capacity loss. Other than that, I MIGHT think about buying it out for the 17K at the end if its worth that much or more on trade in. Again noone knows what will happen, gas prices could skyrocket making PHEV/EV's boom and the values may stay there giving the incentive to buy out and sell for profit or buy out knowing you have all the vehicles history under your belt as well.
Time will tell, very satisfied now with the car, Cant wait for warm weather to swap cars back with the wife and use the LEAF again as my daily. 16mpg gas vs 106MPGe....nuff said
