I'm sure I've read about this car, either in one of The Star Magazines or Mercedes Enthusiast.
I believe the work was performed at a dealer over several years.
I've seen pictures, and the hood has a huge bulge in it as the motor sits too high.
The article went into great detail on the large number of modifications needed to make everything fit. It started as an interesting project by one of the technicians at the dealership for
PR purposes, and the project slowly went so over budget that the owner of the dealer mothballed the project for several years, but was later finished.
