I just took the 1.24% @65mo from DCU without trying to get tesla to ratematch. But to answer your question from what I recall others have said, the process seemed to be: (1) wait till you get your VIN & MVPA from tesla (2) upload them to DCU (3) call DCU and finalize loan. They will then upload your contract to sign (4) don't sign it, instead email it to
[email protected] (5) if you are lucky you get a response back giving you 1.24% for 72 mo, if unlucky either for 60 mo or saying that the DCU mo are different from the 72 mo so no rate match.
