I would say about $35,000 to $40,000 if it has been titled already.
On what your notes would be, let's assume you finance as follows:
Principal $35,000
Interest rate 3.9% APR for 4 or 5 years then an increase to 4.9% for a 6 year loan and 5.9% for a 7 year loan.
Years. Monthly payment. Total payment Monthly note per $10,000
4 $788.70 $ 37,857.60 $225.34
5 643.00 38,580.00 183.71
6 562.05 40,467.60 160.59
7 509.62 42,808.08 145.61
Generally the interest will increase for the entire loan as you increase the term of the loan. If you want to play with loan notes you can google loan calculator and pick from the choices. These calculations are based on rule 78 but your interest may be calculated on simple interest. This is a decision determined by whomever you borrow money from. Simple interest is cheaper.
Keep in mind the market value of the vehicle is what a willing buyer and seller under no pressure to do either would buy or sell the vehicle. What is it worth to you based on needs and not solely desire.
I hope this helps.
