Tips and tricks for lowering car insurance costs in Great Britain

If you’re trying to finesse the lowest price of car insurance in Great Britain, there are a few things to watch out for. Car insurance marketing is clever. Its aim is to make you feel you’re getting the best deal but to maximise the insurer’s profit at the same time.
