Your floor will likely be at least ~$300(scrap)-$2000(good shape). Edmunds doesn't do well with this. Different cars have different floors. For instance, my 05 Prius on the low end runs ~$5900 assuming I keep it in good shape, even if I have ~300k miles miles on it, compared to ~$6600 with ~135k miles. It's low end will drop as it ages, and it'll eventually settle at ~$600-$2000 a couple decades from now. The scrap value will probably be double that of most cars because of the Nickel in the batteries and more copper/etc...
