<prompt> Human: My dad is terrible with his finances, often needing to borrow hundreds of dollars from me for bills, and has no car at the moment. Whenever he purchases one, he doesnt maintain it and lets them fall to ruin - this has happened many times since I began driving and each time he racks thousands of miles on my car, then refuses to pay for the resulting repairs.I firmly believe that one should never cosign for anyone under any circumstances...however the only dealership that would give him the time of day requested that he have a cosigner. I realized that it would be the only way he would leave my car alone, so I very reluctantly agreed. Unfortunately I had too short a job history and wasnt elligible.I am not 100 opposed to being a cosigner for him as Im prepared to make payments should he miss a couple of months, though Id really rather not because my credit score is fairly high and Id like to keep it that way.With that being said, what options does he have available to him as far as purchasing a vehicle goes? Would a Buy Here Pay Here shop be the only shot since he has very little money to put down? Would it be more ideal for him to wait until tax return season?  <response>: Dont.Hes been an adult for, what, at least 2 decades? 3 decades? More? He destroys every asset he has? He has you feeling you should replace what he ruins?What he needs to do is sit himself down and find out how hes going to get from point A to point B alone, with his own money. If he doesnt have it, you shouldnt float it to him. If it means he has to face asking someone who isnt family, perhaps the embarrassment of it will make him take better charge of himself. You should not in any way involve your credit score. You sign for him for this, whats next for what hed want you to sign for?
