I realize there's been other threads on this, but it's been a while and it seems things get a bit in flux. My ISA told me that Tesla doesn't take personal checks over $10k. They also said that ACH or bank checks are fine. I'd prefer not to deal with the hassle of a bank check in case I have to refuse delivery (not expecting to, but just in case). Can anyone confirm that ACH at the point of delivery works out? I'd rather not do it ahead for the same possible refusal reason. If so, I assume all that's needed is routing # and account #? Anything else to be aware of? Thanks!
