To the best of our knowledge, there are no business traders on this forum trying to pass off fake Brides as the real deal, however there have been a couple of private sellers doing so and claiming they 'bought the seats from a mate and they didn't come with boxes or doco' etc etc.
As Antimatter said, while its getting harder and harder to immediately spot the visual differences between the genuine article and the fake at first glance, if you look hard enough, it is still quite obvious (in my mind anyway)
