How do agencies handle mechanical failures while on the road?

If a mechanical failure happens, the established agencies dispatch a replacement vehicle of the same or higher standard right away, usually from the nearest major town. Their wide 24/7 support systems keep itinerary disturbances at a true low level, almost none, really.

Since the fleets are closely reviewed, small troubles like a flat tyre are dealt with quickly by the driver at local garages. When the engine has a more serious failure, the operations team from the main office steps in, and they reroute a fresh car to your place, so you can wait safely nearby at a hotel or restaurant.
