This is the man who built up Britain's most expensive car wash -- from his mum's GARAGE. Car fanatic Gurcharn Sahota, 30, started cleaning neighbours' motors for FREE with a bucket and sponge when he was a teenager. Gurcharn has now built his own Formula 1 style pit garage where wealthy drivers pay up to £7,000-a-time for a luxury car wash. He travels with up to 100 different cleaning fluids that need special clearance at customs. The wax alone he uses costs a cool £8,200 a tub.
