Cargurus seems nice, but it only searches dealerships:
Those are the top five Leaves found near Phoenix, between $7,500 and $14,000 for a 2013 or a 2015 with 10,000 - 55,000 miles. There were eleven more the site considered to be worse deals.
I am having difficulty seeing a reason to purchase an Arcimoto when I could buy a Leaf.
