Re: And where will they be?
We took advantage of that on our first Leaf, in the first of two years lease. The dealer was most surprised that we actually wanted to use the offer - in fact, I think it was the first time they'd had to honour it (and it's the dealer that pays, not Nissan). Anyway, we got to drive a mobile advert for a Basingstoke car dealer around the Isle of Skye for two weeks. I did say to them that they probably wouldn't get any new customers--.
We are now on our second Leaf, and the offer wasn't repeated, so not sure if it's still there or not.
However, it was a good idea - along with the free recovery if you go flat (they did say "don't use it too often"!)
