Besides the 60-day lock, is there any advantage to going through Alliant directly rather than through Tesla Lending (which deals with 4 banks apparently, not sure if Alliant is included)? I see in the details that Alliant has additional stipulations on payment to get lowest interest rate. I also wonder if they include any penalties for prepayment or extra payment of principal, and/or a minimum time you must keep the loan product open before payoff. The Tesla Lending agreement prohibits all that.
