One thing I did not like about those DTM CLK's was the lack of of rear inner fender. If you do not scratchbuild them the whole back end around the wheels has a terrible see through effect. The real car has this area totally enclosed in carbon fiber. Also if you look down in the engine bay the headers end in front of the fire wall. I added strip plastic on the wall that sticks out just enough to hide the ends. The fit of body on to finished chassis is also very tricky. I hope this info is helpful to anybody building it.
