I just want to let the guys/gals who may not be in the position to pay cash know that paying cash is not always the best way to go.
If you've been responsible with your credit and would qualify for very low or even zero percent financing, and have your money in an interest bearing account, you could actually make money on your money by making payments rather than giving it all to Chevy.
Simple example is: you are awesome and qualified for 0% (yay!) financing and have an interest bearing checking account with that money you were going to pay for your car with, you will earn interest on that money by making payments rather than giving it to Chevy all at once.
One thing to think of - and it is sorta backwards thinking - is that while, yes, if you can get a 0% loan and keep the cash earning money while you make the payments is this: I have not found an investment (while keeping the money available for an emergency) that even comes close to keeping up with - let alone - outpacing inflation. So, in my mind, it is a moot point (for me).
There's another great way to think about doing it the way you mention, though - if you have that big lump sum sitting in your account, paying monthly on the 0% loan: You'll have that money as an emergency fund, should the sh!t hit the fan in your life. Definitely a good way to go as well.
But...
At this point in my life, I am fortunate enough to be in the position where if I want something "big", I make a plan and start saving ahead of time. I'm this way from plenty of bad experiences having two car payments, a mortgage, student loans and credit card debt. Living paycheck-to-paycheck, not saving - not being able to save!
Over the years, and losing most of what I owned between two failed marriages, I know credit is a necessary evil to live in today's world. Many people in this forum needed a dependable car that got good fuel economy because of their job or school or life.
So, short story long - I'm terrified of getting money on credit, and I'm lucky enough to be able to save for big purchases before I need them.
