Years ago, I had a car that ran great. But when it hit 120,00 miles, it began costing me more in repairs than payments on a car that didn’t need repairs would cost. I had a co-worker at the time who was married to a car salesman, so I went to see him. As we looked at used cars on his dealer’s lot, he told me about a 3 year old car they had just bought back. In the 36 months the owner had the car, the oil had not been changed even once, and they only brought it in because the engine seized up because of that neglect. Rather than tell the owner it was their fault, and they were out of luck, however, the dealer offered a great trade-in price if they wanted to buy a new car. They agreed to the deal, and I ended up with a 3 year old car (with payments set at the value of a three year old car), but a brand new motor courtesy of the dealer.
