People make the mistake of thinking a credit report is a report card on one's debt repayments. That's true to an extent, but more importantly; a credit report is a dossier on a potential customer that can be factored, specifically for an anticipated profitability of the customer. When one applies for credit and and their credit report is pulled, the lender is evaluating how much ROI they'll make on this customer and the risk factor. To have "good" credit, you should be paying interest payments somewhere in a series of years, be it auto, home, or CC. Without there, there's no history and thus, a lack of confidence in the risk calculation.
