<prompt> Human: I bought a car a few months ago even though I didnt need it because my old one, well my dads old car, was working just fine. Im very used to saving at least 400 per month and I made a bad choice by picking a debt for 369 a month. As you may realize, living on such a tight budget has me going crazy and Im moving in with my girl in a few weeks from now, so that means spending more too. My short term solution is to sell the car, for which I would get about 10K free from debt and buy a motorcicle, put the rest in a index fund. My gf has a car so at least we would keep one for trips, etc... Please let me know what you think.  <response>: put the rest in a index fund.Wrong, unless youre excluding information here. You say youre used to saving 400 a month... What do you have saved right now? Ifwhen you sell your car, youre more than likely going to be upside down and have to fork over a chunk of change in order to get the title released. Dont expect to sell the car for what your loan amount is worth. It rarely works like that.You made a choice and financed something that is more than you can handle. It is not uncommon. You need a laid out budget. If you had one, you would have known this was a stupid purchase. You need more income. Especially if youre about to pick up MORE responsibilities. Job change, more hours, second job.. something. Get on that immediately. Dont even think about investing into indexes when youre already so tight on cash. Get rid of the car, get the debt settled and work on getting money saved before you even begin to think of investing.
