- Compare across all 10 brands. Price differences of 30-40% for the same car class on the same dates are common at IAD.
- Skip prepaid fuel. Self-fill at a station 3-5 miles from the rental return is cheaper in 85%+ of cases. FillItRight calculates the exact gallons.
- Decline counter insurance. Your credit card or auto policy almost certainly covers it. InsureItRight tells you which.
- Photograph everything at pickup. Every panel, the fuel gauge, the odometer, with timestamps on. Saves you in damage disputes 30+ days later.
- Read the agreement. Especially the fuel policy section — that's where the $9-$11/gal refueling charge hides.
