I've used the same garage for over 10 yrs, they never rip me off, lend me a loan car & always fit me in in an emergency.
they are brilliant!!!
over the last 10 years I've never recommended them to anyone.
when you read the American boards it says make your customers chearleaders who shout from the rooftops about your great service, but I don't think it works with the British, we are more private & reserved.
