I got my DTM race tickets on Ebay.
I saved more than 50 Euros compared to the official price. I got them for Gold category (second row or something on the grandstand, completely amazing view over the chicane) and extra tickets for the paddock. Now I will see if I can get my new friend interested in racing. I'm sure he will love it.
I just need to find out if there are some Argie drivers for him but I really doubt it.
