If only he'd made a full-scale model, it would be worth an absolute fortune.

My friend and his girlfriend both works at MB. The story I heard was this guy did an amazing job with the replica (needless to say). One would think that he got a job offer from MB, but no.... not even close.
The guy made a terrible mistake. He took the replica to an auto show where MB was going to present the real SLR. He had the car under a sheet of cloth and presented the car outside of the autoshow. The presenter for MB saw what happened and thought he was fired and was not informed. The guy made a call to the headquarter about getting fired and was quite upset. That's when MB learned that someone had created a replica of the SLR. The guy was being sued for patent infringement.
This is what I was told back in Oct of 2003 at a VW gtg from a friend who works at MB.
