I bought a 2006 Silverado at the beginning of January 2016 and it had 183,000+ miles on it and the dealer approved me at a bank with a ridiculous interest rate. Before the end of January I refinanced with DCU and got a 3 year loan at 2.74% interest (DCU initially offered me a 4 year loan on the phone when they called saying I was approved but I told them I wanted 3 years instead)
To answer your question, yes, you can refinance a vehicle with over 150,000 miles on it.
How upside down were you in your deal with DCU? And, what are you scores like?
Just curious.....I'm kind of in the same boat!
Thanks. Any information would be greatly appreciated!!
