General Motors is launching its MasterCard or Visa credit card this month, with an APR of 19.9 per cent and no annual charge. Those moving their credit card accounts receive a 5 per cent rebate on the amount transferred.

For every pounds 100 spent with the card, pounds 5 is credited to a rebate account, which entitles users to a yearly pounds 500 discount on a Vauxhall vehicle.

A 24-hour customer inquiry line is open on 0800 565554.
