This is my first time getting my car financed, so Im not completely sure how all this works. I bought my first car, a 2010 bmw 328i in march 2013 at a cost of $20,000. I have $16,000 left on my payment and I received an offer for $17,500 to sell my car. I am wondering if this puts me in the position to be able to get a bigger loan, thus a better/newer BMW or if I am better off sticking to the car I have now? I really want to buy a used 2012 or 2013 328i.
