Debating trading my 08 LTZ 5.3 with 62k on it for a diesel. I still owe 19k on it. So I'd likely brake even on a trade. Don't really want a monthly payment over 400. I do have a 700+ credit score so financing is no issue. Is it doable with a NNBS or will I have to go to a NBS. Also i really don't want a truck with 5 million miles on it even though it's a diesel. Is there anything I should be weary of with the old diesels. I haven't done much research into what problems they have and what to look for.I'm headed there now as I'm bored at work. But would like anyone's recommendations on the issue.
