These two images come from a small catalogue by a German company called "Schulz Tuning".

Schulz appear to have gone out of business since I can find no trace of them on the web. However they seem to have sold "AMG like" bits to add onto your car.

The top image is of a stretched W123 limo with a special W126 SEC like bonnet with grill attached. Also added are front and rear spoilers, door ledges and probably a little bit of lowering of the suspension.

 

The lower image looks at first glance like a four door SEC from the 80's. However its another customised W123 with all the trimmings.

If you click here you can find out how much all these extras cost back in the 1980's...(prices in DM of course)
