I checked in here today expressly to see if you had made any mention of what you did at the end of your tenure with the 2014. You were a month or two ahead of us getting into ours, so naturally we're approaching that point now. We did not receive an offer in the mail akin to yours mentioned in August.
Naturally, our call option on the car is out of the money, so we don't plan to exercise it, although we do still like the car.
The new lease offers for the 2017 model seems to apply, if I'm reading and understanding properly, only to the examples without the full gamut of safety and convenience options, and not pro-rata to all B250e available. For us, that could be a deal killer.
CarMax seems to offer a decent selection of used 2014s, but their ask prices are around the purchase option strike prices from the original lease agreements. One born every minute, and all that, but having an idea of what these are going for at auction makes that seem like a gouge - especially given that the way that they list them online requires that the buyer be more product savvy than the seller in order to even discern which features the cars have.
Perhaps, as we prepare to turn them in, we should submit our vins here for those looking to pick up one with a known history. Knowing whether a particular car has been a victim of the sudden stalling and no-start problem, the results of annual battery certifications, maintenance performed, and software recall performance status would be of interest to some buyers here.
