I bought a quad from a person, long story short. He took the money, never paid off the loan. The bank owns the quad and is going to repo. the ATV.

Is there a legal way I can go about getting the account information and copy of information for proof that the account was never paid off? I have been in contact with the bank and they know who I am, but can I legally get that information for proof in court?

Do I get pictures and a written contract/letter that the quad was repo’d for failure of “previous owner” breach of contract?

I am suing for the amount I paid him (2500). Can I also sue him for the amount of the background check I had to buy to get his address and phone number since he lied about his location?

Any other ideas would be helpful and greatly appreciated.
I have bill of sale .. and the quad has a vin number and the bank has the account on file still.
my little brother is also witness to the transaction
