I did it for 84 months at 2.99% — My work pays a certain dollar allowance per month for any car that I wanted. I didn’t want to come out of pocket at all unless I wanted to overpay and pay down the principle with extra money when it’s convenient.
I also have no intention of keeping the car for 7 years, so I bought a barely used M3 and saved on depreciation.
As a whole though, I agree that financing a car over 7 years is wild!
