Need your help on Opel Team Holzer

My next project as posted is on DTM2000 Opel Team Holzer and I am doing some research on it.

Unfortunately, as much as I have searched, I cant seem to get the inside interior pictures of the sides, rear, front views of the actual racing car.

I have search www.dtm.de, dtm.com, keyed in the actual driver's name Joachim Winklehock in search engines and still left with very little or not good views of the car itself.

If you stumble across good pics of the actual version of the car, please let me know.

The version of the car is this one which was taken off tamiya's webby:

Thanks in advance for those who can help!
