Next, reserve the smallest car you can.

And if the rental agent offers you an upgrade, don't take it unless it's free.

"Chances are, they're offering you an upgrade either to make an extra couple of dollars a day or because they don't have the car you reserved on the lot," explains Jeannine Fallon of "They want to get you to pay for something they would otherwise have to give you for free."

"If you have car insurance and you have a credit card, you probably don't ned any of the insurance that a rental car company is going to offer you," Fallon says. "Read the small print, call your credit card company, call your car insurance company and find out. Chances are you're going to be able to save that and sometimes, it's 50% of the car bill."

Also, don't select the pre-paid gas option. The per-gallon price is usually much more than you would pay filling up at a gas station.
