How to avoid a pile-up of rental car fees Stacey says she rented a car and ended up paying more in fees than the daily cost of the rental. She asks: Is there any way around this? There is. The trick is not letting the rental-car company up-sell you on all the add-ons you don't need or want. ASK LAZ: Smart answers to consumer questions The biggie is what's known as CDW -- the collision damage waiver -- which can add $30 or more to the price of your rented wheels. The rental company may make it seem like you'd be a fool to drive off the lot without insurance. In fact, your personal car insurance probably covers most accidents, and your credit card issuer will provide an extra layer of protection. Check in advance with both to see what's covered and what's not when you rent a car. The rental company also will try to get you to agree to various bells and whistles. These may or may not make for a more enjoyable trip. But they all add additional fees and thus could stand some reconsideration. The GPS system, satellite radio, a toll transponder -- each comes with a charge. Ask yourself how badly you need these extra goodies. One last tip: Think about picking up your rental at a location outside the airport. This might be a bit of a hassle, but it can help avoid an airport concession fee that can add 10% or more to your bill.
