My sister's husband needed a new (used) truck for his business the week before last. His old one died with 245k on the odometer. She didn't want to deplete all their ready cash right before Christmas, so naturally, she called her frugal sister for advice. I suggested she get a loan for at least part of the purchase amount. Based on what I'd read here, I recommended PenFed. She applied and was approved in the same phone call. They offered her 2.49%. The same day, a friend mentioned having seen a truck that fit their checklist at a dealer in town. The looked, liked, and negotiated a price they were comfortable with. They told the dealer the rate they had been quoted from PenFed, and the dealer matched PenFed's rate.
She plans on paying it off in a couple of months. Since it's a legitimate business expense, I'm trying to convince her to let it run at least a year and save/invest the difference, but I doubt she'll last that long. The great thing about car loans is that you can pay them off whenever you like.
