They will pay the difference between the Motor Insurance payout and the Invoice price of the car.
The Future45 Group have developed a suit of gap and warranty insurances to discerning customers who know what they want but don't want the salesmen, brokers and motor dealers taking their cut to provide the insurance.
In conjunction with the Red Sands Insurance company they provide these services through their dedicated web sites cutting costs even further and are able to pass these savings on to their customers. They claim you can save up to 75% of the cost of Gap Insurance because of these well tailored policies delivered direct to you through their web sites.
