Upgrade: Travel Better says most car rental places will charge drivers under 25 an additional $25 per day, but there are a couple of things you can do to reduce the ding.

Try local shops: Mom and pops might cut you a break, especially if you mention and bring in a copy of your spotless driving record.

Really, though, there's not much you can do, except get older. — BEN POPKEN
