At the end of every car rental, there's always one stop right before return. You should always be thinking of how to minimize the cost of your fuel, since prepaying for a tank of fuel is never a good deal for the renter, and returning with less than a full tank is an even worse decision.

There are times when you may need a one-way car rental, where you rent a vehicle at one location and return it at another. Although once uncommon, almost all rental car companies now offer one-way rentals. In fact, about 13 percent of all AutoSlash rentals are booked as one-ways.

Return your rental car with a chipped windshield, fender ding or paint scratch? Here's what's to expect: The rental company will file some form of "Vehicle Incident" or "Condition Change" report when you return the car. Then you leave the rental car location and wait while the rental company assesses how much to charge you—and it will always be much more than just the cost of repair.

But Hertz offers a kinder, gentler solution. When there's minimal damage to a rental vehicle at Hertz, there's frequently an option to quickly resolve the claim at the time of return. A member of the AutoSlash team recently ran over a piece of metal debris on a highway and was able to resolve the issue of a damaged tire for just $40. Try purchasing a tire and having it installed at a local tire shop for 40 bucks.

Renting a car for the first time can be simultaneously exciting and scary. A car rental opens up a world of possibilities when you travel, but there are some pitfalls you want to avoid. We're here to make sure you feel that sense of adventure without the downside.

For starters, know that simply booking a car reservation is usually a low-risk proposition more akin to booking a hotel room than booking an airline ticket. There are two kinds of rates: Those you pay when you pick up the car and prepaid rates. The first time you rent a car, you will probably feel more comfortable booking a Pay Later rate, which will have no cancellation penalty in case you need to change your plans.
