Car hire through the MoneyMaxim will normally include Collision Damage and Theft Waivers and Third Party insurance. You can find some cars with zero excesses but US $750 is more typical on a small family car. Any damage to tyres, glass and the underside of the car will be excluded even if you have a zero excess rental agreement.
Car hire excess insurance can protect you from these excesses and charges for excluded items at a fraction of the cost of purchasing additional waivers at the car hire desk.
