Gurcharn Sahota, a 30-year-old accountancy graduate, is offering the world’s most expensive car wash service in the UK – charging up to £7,200 per vehicle.

Mr Sahota, who lives with his parents in Derbyshire, has converted their double garage into a hi-tech workshop. He has lined the walls and floor of the double unit with specialist tiles imported from Italy which help reflect flecks of dirt on the cars.

Each vehicle takes up to 250 hours to clean, and his premier service includes polishing and buffing every inch of the car inside and out five times. After spending hundreds of hours cleaning by hand he uses a £5,000 computerised microscope which examines the car for blotches and scratches. A buffer is linked to a highly sensitive paint gauge which scans the car to prevent patching on the bodywork. Finally, he uses a specialist clay which he rubs over the bodywork to remove any imperfections.

Since he started the business five years ago, Gurcharn Sahota has washed hundreds of supercars including Ferraris, Lamborghinis, Rolls Royce and the Le Mans-winning McLaren F1 GTR.
