Always pay cash if you can...no payments! I absolutely hate making payments on anything, so only buy cash - sort of - we use our credit card for purchases and then pay it all off at the end of the month.
For those making payments on cars - when the car is paid off, keep making the payments, but make them to your bank account. Don't treat it like you just got a raise unless you MUST to keep a roof over your head and food in your stomach. I did that after I paid off my first new car years ago. When it came time to get a new car (old car was aged 10+ years), I had the money in the bank. And I kept making the payment into my bank account.
Enjoy your new car!
