I'm doing some financing for our future (my wife and I), and we want to purchase a used car - we'll be getting a loan, but along with the monthly payments we'll be making, we want to know what the 'real cost' each month will be for paying for this car - maintenance, gas, sales tax, and monthly insurance premiums (For New York State, Albany County).
How can I find out what these 'additional' costs will be when looking to buy a car?
