Thanks again, good questions.
Right, but if I were to finance with a dealer…I have confirmed there are dealers who will finance me in my area for this vehicle, I just want to know what I should expect.

Auto finance is what I do for a living and you need to go to your own local bank or credit union, this vehicle is way to old and has to many miles on it for any major lender to even consider.
Everything else looks OK.
