I'm one of "those people" who took out a 72-month loan on a vehicle. I'm not saying I am right in my thinking or opinion, but this was my logic and plan. I drove out of the dealership 2 years ago with a 50k vehicle with $0 down and 72 monthly payments.
I didn't plan on taking 72 months to pay it off, I wanted the lowest possible payment in case my financial situation changed in the future.
I had the money for the down payment, but I didn't offer it at the purchase. I waited several months until the vehicle showed up on my credit reports and them paid down the loan by 5K showing as a 10% reduction in the loan. This alone gave my credit score a bump.
2 years later the vehicle is 50% paid off through an accelerated payment plan. I have the base payment on auto-pay, and when my finances warrant, I pay extra on the principal. I've been told from some advisors that because I've paid it down to 50% and the loan is over 2 years old, it isn't as relevant in my credit scoring any more. It was suggested to refinance the vehicle or purchase another vehicle. I'm not inclined to do that yet, and probably won't do either.
This worked for me, and it worked for my financial situation, but it may not work for you. I just thought I would share where a 72 month payment plan could be a sound financial and credit score strategy.
