I've never financed a car (or anything other than credit cards) before, so I had a few questions about the financing structure that Tesla uses, and their website hasn't really been helpful. Basically, in doing my research I've found that some type of car loans are calculated by tallying up all the interest you will pay over the life of the loan, and then dividing up that number plus the principle over the length of the loan. The advantage (for the bank) of this method is that it guarantees that the person paying the loan will pay the full interest amount, regardless of whether or not they make larger payments to finish up the loan earlier. Is this the way the Tesla loan works, or is it like a more traditional loan? I was planning to occasionally make additional payments towards the principle and therefore reduce both the number of payments I'll have to make and the amount of interest I'll have to pay. I'm hoping this will be possible. I know that the Model 3 APR and loan information isn't readily available yet, but I figured people that have financed Model S or Model X can answer these questions, as the answer is likely to be the same.
