<prompt> Human: I am a non-resident professional making 100k a year in the bay area. I am planning on buying an expensive car like bmw or audi. Since I started workingearning only 6 months back, is it advisable to invest 40-50k on a car or buy a used car for 10-15k and wait a couple of years. Is it advisable to finance using loans 2-3 interest rate or wait till credit history builds sufficiently. No debts, loans at present. Starting from scratch in the US.  <response>: A car is not an investment.
