BMW and Mini dealers in the UK are increasingly using free seven day motor insurance policies to help seal the sale.

RBS Insurance, which provides the product for the franchised network, said dealer usage levels are continuing to grow with more than 100,000 seven day policies issued in 2008.

Around 15% of those customers go on to buy annual cover from RBS Insurance.

Leanne Thames, insurance product manager at BMW Financial Services, said: “Seven day complimentary insurance has proven to be a real benefit to our dealer network adding value to their customer service proposition and supporting our ambition to grow our motor insurance portfolio."
