Let's think about what an insurance company might do if , through no fault of your own, somebody smashed into your Leaf and totalled it.
IMO, you would want your car replaced with another Leaf. I know I would. Which would mean going to the back of the 1 year wait line. Or could you push the insurance company to find a similar Leaf in the used market, at whatever price it took to get it.
You would be dealing with the 'at fault' drivers insurance company, so it would be their responsibility to make you whole. Waiting a year would not be acceptable, IMO. Any precedent for how this would be handled ?
