In the unlikely event that you sustain damage to your rental car, inform the company as soon as possible. In general, quotes for the repair of rental cars in Ireland are generated using the Audatex estimating system, which calculates the repair cost based on motor industry standard Thatcham Times and times supplied by the vehicle manufacturers. Audatex is used by the majority of approved repairers, insurance companies and motor assessors in Ireland.

Where possible, repairs are carried out during quieter periods when there is no additional cost in taking a damaged car offline.
