old new car

Last month I went to the union bank and applied for auto loan, and I got approved with annuity rate of 2.9 percent. I was really happy because it was the smallest interest that  I received from any banks. I supposed to get a new car this month, but I still try to push through it. I know that I was approved for the loan, but I was thinking about the monthly payment for  years. Instead, I bought an old car from my friend and still works good. I like it and I bought it cash so I have no monthly payment yet. I like to drive a new car, but I hate the payment. I hope my old new car will last for a few months.
