NAvy Federal will Loan in excess of $50 K on an old car.
Talk to your bank. Find out what they use to value old cars. mY other bank used the CPI [ cars of particular interest] Guide.
NFCU used the NADA collectable car guide [ can find on
www.nada.com] for both my cuda and charger.
If they can justify the value of the car compared to what you are asking to borrow and you have decent credit, and a good debt to income ratio, you will be able to get the loan. Try a credit union if you have one nearby, their loan rate % is usually less than a bank.
