Sure, I get that all you care about is your monthly payment, but in your exact scenario the payment is actually $2,200/mo not $200. So yea, interest rate matters a fuck ton.

If you are paying a crazy high interest rate on a lease on a high dollar car, even with a very high residual, you are getting ripped off and are better off buying the car, financing it yourself for 2 years, and selling it. Paying a very high interest rate on a lease will make it very hard to get a good payment.
Tl: dr Interest rate matters, it’s not all just about the final monthly payment in smart decision making. Though salesman must love you haha.
