That's what I've always heard. I think I benefited from buying towards the end of the year. I spoke to a couple of people who bought recently from the same make dealerships. They had good credit, went through credit unions and ended up paying 4.9%.I always use credit unions. Back in ‘10 my rate was 4.8 with a credit score in the 500s
I intended on checking with credit unions. But I didn't feel like they could do better than 2.9% on a use car.
