Hi just about to purchase 2017 30kw Leaf 22,000 miles for fair price from Nissan Dealer. They tell me that they check the health of the battery and use a star rating which strikes me as not all that helpful. I've told them I will do a Leafspy check and just wondered what would be an acceptable minimum - I would say 93% but would really expect at least 95% from what I've read from this forum. Mos grateful for views.
