you can ask Marcus Hotz directly
www.horag.com
I would sugest a fax or email then follow it up with a phone call
i tried to ask Marcus some car history question in February he replied that he cannot remember all the cars and has some records but he was busy with current programme
you can also ask Franz Konrad directly
www.konradmotorsport.com
I think you will find it easy to get info as they all speak german!
