With interest rates so low plus the benefit of gap insurance, I'm inclined to finance 100%. One thing - what about the $5000 nonrefundable deposit? Has anyone financed the whole amount? Did you give Tesla a bank check for the whole amount and later receive a refund from Tesla of your $5000 deposit? UPDATED: I ended up doing exactly this and it worked out fine. I gave Tesla a bank check for the whole amount and about 4 weeks later received a check back from Tesla for the $5000 deposit.
