Refinancing makes sense when:

• Interest rates have dropped since you got your original loan.
• Your credit score has improved, making you eligible for better terms.
• You want to lower monthly payments to improve cash flow.
• You need to change the loan term (shorten or extend repayment).
• You want to remove or add a co-signer on the loan.

💡 Pro Tips for Maximizing Your Auto Loan Savings

• Compare multiple lenders before refinancing to get the best possible rate.
• Check your credit score—higher scores often qualify for better rates.
• Avoid extending terms unnecessarily, as longer loans may increase total interest costs.
• Consider all fees—make sure savings outweigh refinance fees.
