It seems like battery replacement cars like the first gen Nissan Leaf's are hard to come by. Based on the videos from Rich Rebuilds' channel, Tesla replacement parts are similarly difficult to source from the manufacturer. For long term ownership, the ability to replace one of the battery modules versus the entire battery pack is still up in the air.
No doubt that this will get better with time, but I was really hoping Nissan would do a better job of providing EV parts support. I heard that older Prius NiMH battery pack replacements are quite common (in the US at least).
