Our staff will be pleased to assist you with the rental extension. This will be subject to availability and rental rates at the time of your request, and signature of a new Rental Agreement.

So if you keep your car longer than scheduled without signing a new Rental Agreement, you will no longer be covered by the insurances and covers you chose initially.
