<prompt> Human: I try to make this short and bittersweet. My brother in law bought in July a used 2010 VW Jetta Wolfsburg Edition for 17,500. In addition to that he took out GAP insurance and some kind of maintenance contract. The overall sum totaled to 20,500.His credit is somewhere in the low 600 I believe 620. The dealership got him approved for a whopping APR of 18 over 72 months. Mind you that this is about 35k at the end. Absolute usury to me.Anyway, he nets in about 750 bi weekly and gets about 1,000 from other sources. That makes a total income of roughly 2,500 per month. His rent is 475 utilities included. He does not have cable or internet but does have Verizon prepaid phone for 60 bucks a month. Insurance on the new car is about 95 dollars I believe. The numbers dont look that bad on paper. 2500 income, 475 rent, 95 insurance and 475 car payment. What really irks me is the whopping 18 APR. The dealership told him that he could refinance after 6 months up to a year. Here is the catch. Lets say a local credit union would refinance. Theyd give him about 12,900 dollars with begging maybe 13,900 according to the teller. He owes 20,500 dollars and the payments he made so far almost solely went to the interest. That means he needs to come up with the gap of 7 - 8,000 dollars, right? Thing is, he is is really bad with money. Give him 50 bucks a day and he spends it. Give him 500 and he spends it. There is no way he can save any money. So far, I took from each pay check 100 bucks to hold on to it so that he has some money for food at the end of his pay period. So, my question is. What should we do in this situation? Sell the car privately and count our losses? Refinancing is so so so far away. I find it morally wrong to pay 35k for a 17,500 car; let alone the dealership usury!Thanks rPF:edit:Thanks all for your input. I understand the question as to why I am handling his money, why am I even involved in his financial life. Well, there is a bit more to that. He is an adult actually 8 years older than me but with the financial capabilities of a child. He suffers from a mental illness that makes things very challenging. Socially, financially, etc. I try to help him without being too bossyinfluential. My wife his sister tries to support him socially, Ill help with the finances. Id like to not be involved but thats currently out of the question since we are the only two people he has.I like uextremelyCombustible advise about calling the maintenance contract companies and see what they are up to.Thanks again and I know its not my taskduty to do things for him but he cant do them for himself :  <response>: I find it morally wrong to pay 35k for a 17,500 car; let alone the dealership usury!Im going to go with WC Fields on the morality of this one. Your brother being the subject in question.Hes an adult, he made a decision to buy something he couldnt afford, financed it at a very high rate because he is financially irresponsible, and now he needs to deal with the consequences of that decision. Hopefully he will learn something from this.Your suggestion to save is good, but if he isnt going to do it then it might not be sustainable. He could just try to accelerate payments; pay like 600 instead of the 475 as the surplus will be applied to principal. That way, he isnt walking around with money with the risk he will spend it.
