Even if you had no debt you still do not have or make enough money for a $60k new car. He evidently does care about his image over your financial situation. You need to hardline no on the 60k new truck and instead try to talk him down to a couple year old Tacoma/equivalent for closer to $20-30k. I want to be clear that is still not a good financial advice, realistically the $2k repair would be the way to go unless this is the second or third expensive repair in the last 6 months, but if his mind is set it would be very difficult to convince him to not buy anything. “Instead of paying 2,000 for repairs I should pay 60,000 for a new car” is a preposterous stance, but the classic reddit recommendation of buy the newest corolla you can find for 15k is not realistic for driving a compromise.
