The importance of these often-forgotten add-ons cannot be overstated, especially for families residing in flood-prone areas or frequently commuting through waterlogged regions. For instance, the 'Engine Protector' add-on is vital because standard comprehensive policies often exclude damage caused by water entering the engine. If a car's engine seizes due to driving through deep water, this add-on can cover the repair or replacement costs, which can be substantial. Another critical add-on is 'Return to Invoice' (RTI). In the event of a total loss of the vehicle due to flood or any other covered peril, RTI ensures that the insurer pays the original invoice value of the car, including registration and road tax, rather than the depreciated market value. This can make a significant difference in the ability to purchase a new vehicle. Neglecting these can turn a manageable vehicle repair into a crippling financial burden, impacting family budgets and mobility.
