I looked into that and there was exactly one vehicle available and it was something like $7500 due at signing to get that $849/mo payment, IIRC on a 36-mo term, so really it’s more like ~$1058/mo, which makes more sense.
Still a lot of discounts on EVs if you know where to look. Definitely lease; these will depreciate like bricks after the batteries get used up and are down below 70% capacity. I’m not sure how financing companies are doing the math but their expected values at the end of lease terms feel wildly optimistic. My guess is some degree of mfg incentives to push EVs combined with models that took too much pandemic pricing into account for used vehicles. If you can get a good money factor on the lease, go for it.
