A few points on a credit score can mean the difference between a lender offering you a prime rate reserved for the best credit risks and the worse interest rate offered to less than prime customers. This may amount to only a few percentages in different loan rates, but this can make a huge impact, especially on a large purchase. For example, a few percentage points on a long-term fixed-rate loan can mean the difference between tens of thousands of dollars saved - or tens of thousands of dollars overspent.
It is in your best interest to boost your credit score by every percentage point you can and to fight for the very lowest interest rate loans you can. After all, if you have larger payments each month due to a higher interest rate than you deserve, it will be harder for you to repay your bills. Also, you will qualify for fewer loans if you have higher-than-needed interest rates, as you will be able to afford fewer of the larger monthly payments.
