The price is very cheap but unless you live in an area experienced in Leaf repair, CA, WA or maybe some areas in CAnada, including Montreal or Vancouver, I'd probably steer clear. Not a lot of people are experienced in Leaf repair and if you just go into a local Nissan dealer you could end up spending lots of time and money that would far outweigh your cheap initial price.
