I went to the Kahn HQ about 6 years ago and they had a Lamborghini Diablo in their warehouse with flat tyres - When I asked why the tyres were flat, I was told that they don't often use the car, as it's only used to pick people up from the airport when they want to look important and professional!!!
The head man openly admitted that he started out in business by ripping off other people's bodykits and selling them cheaper. The same with their alloys - The well known Kahn RSR wasn't actually their design.
Credit to them for convincing the world that they're Aston/Bentley/Range Rover specialists though! It's a long way from copying an MCR bumper!
