The $468 was for a $25,000 loan at 4.74% for 60 months.....
Here is what other amounts (payments) would be for a 60 month loan at a 4.74% rate. Keep in mind that this is just a straight computation......if they do something "creative" with your financing, the payments may change, but at least you now you have a ballpark payment amount. Good luck.
$24,000 loan would be $450.06 per month
$23,000 loan would be $431.30 per month
$22,000 loan would be $412.55 per month
$21,000 loan would be $393.80 per month
$20,000 loan would be $375.05 per month
