MERCEDES-Benz will not be joking when it introduces the ultimate car warranty plan. Bosses at the German company were deadly serious at the Geneva Show when they revealed a standard package which will allow owners to set a remarkable free service in action each time they run out of petrol.

Under the service and support package to be known as Mobilo, owners who suffer the inconvenience of a flat tyre will also be able to call out the round-the-clock service to get them back on the move again at no cost.

Though the standard Mercedes-Benz warranty only lasts for only 12 months, Mobilo will be operative for three full years from the date when a new Mercedes is purchased after April Fools Day.
