<prompt> Human: CONTEXT:I am 25, live with my parents still, work full time, starting law school in the Fall. My only expenses are car payment, food, gas, and recreational expenses right now. My parents are fine with paying my car insurance cell phone and do not charge rent.The law school Im attending is in state so I will be living with my parents another year or two at least.My current salary for my full time job is 35k per year gross. When I start school I will bump down to part time where Ill be making roughly 800month at first at least, I will bump up hours if possible with school schedule.Currently I drive a car that is financed at a 1.9 interest rate with 12,500 left on the loan it was financed at a 60 month term at a monthly payment of 390. I do not enjoy driving the car, find it very uncomfortable, and it is starting to have some problems that are not under warranty.I am considering trading in this car for a certified pre owned car. Roughly the one Im looking at would be financed for 60 months at a 2.9 interest rate. The only way I will actually go through with it, is if the payment is under 400 a month, similar to my current payment. Am I being responsible or irresponsible here? Looking for outside opinions  <response>: Spending well over half of your income per month on a car is absurdly high.The 20410 rule is a good guideline for car purchases that involve financing, though there are exceptions.- At least 20 down payment including trade in value- At most a 4 year loan term- At most 10 of your gross income spent on the loan payments plus insuranceAt the point youre at, downsizing to a 3000 car that you pay cash for might be a good idea. This assumes that you have equity to cash out from your current car. If not, then sticking with it until you can sell it to zero out what you owe would be prudent. Whatever you do, dont roll over negative equity into a new loan.
