<h1>Interest rate variation on used car loans hinges on credit profile, tenure, vehicle condition, and lender policies.</h1> Interest rate variation on used car loans arises from borrower credit profile (notably credit score), loan amount and tenure, vehicle age and condition, margin money, lender policy differences, and macroeconomic factors. Borrowers can lower rates by improving creditworthiness, increasing down payment, opting for shorter tenures, shopping across lenders, and negotiating terms. Product features-such as advertised starting rates, high financing percentages of vehicle value, flexible tenures, simplified documentation, fast approvals, and online tools-are key comparators when choosing a used car loan.
