For my upcoming Model 3 purchase, I'm trying to figure out what would be the best deal for me. So I was on a car loan calculator website and figured the cost for some numbers. I plan to get a base Model 3, maybe with the big battery. I probably won't get the D, and I don't plan on getting any other fancy options. My credit score should be right around 700, and I got a 6% interest loan on my '11 Challenger R/T when I bought it in March '15, but then again that was a used car compared to a new car here. Never been late on a payment for that one, or my previous car loan, so I should have a good payment history for that. So for 35000, 39000, and 43000 loan amount, and 6% interest, figured for 60 and 72 months, here's what I got: 60 months: 35K, 677 payment, 5599 in total interest. 60 months: 39K, 754 payment, 6239 in total interest. 60 months: 43K, 831 payment, 6878 in total interest. 72 months: 35K, 580 payment, 6763 in total interest. 72 months: 39K, 646 payment, 7536 in total interest. 72 months: 43K, 712 payment, 8309 in total interest. If I got the big battery, plus the fees and delivery and sales tax and gap insurance, I'll likely be in the 39-43 range for total loan amount being financed. I kind of wanted to go with a 60 month loan to minimize the interest I pay, but it seems like if I go with 72 months, my monthly payment will be smaller by an amount, that when multiplied over 72 months, means I pay less in payments than what I pay more in interest. Yes, I'll get a tax credit, and I plan to apply it to the payments, but for now, I'm not assuming that extra money into the calculations. Any suggestions?
