Thanks for confirmation. Based on the numbers you provided (and assuming I didn't make a mistake in my calculations) I got this.
If you're not planning to invest the best option is of course buying with cash (assuming that you need to pay back EV tax credit for early lease buyouts).
If you still prefer to finance and not invest then leasing is the best. $7.5k even with pretty bad money factor gets you far.
If you're investing then after 72 months your 5.25%-5.5% loans are the best options. Monthly payments are only $154.66 - $169.85 higher than lease payments, but you keep more money over 72 months period to grow in your investments.
