Hello Guys, I'm new to this forum. I was wondering does Audi race it's RS4, S4, S6 models? I've seen some of the LeMans series and was shock not to see these fine cars not on the track. Now I've heard the rumors in the past about a "Unfair advantage" and I'm still trying to figure out what exactly that is. Does the racing heritage begin and end at the top line or is there a trickle down affect? What is the reliability factor, are the parts expensive? I remember a report that said the American automanufacturer quality has now caught up and surpass German cars, is it true? I know these questions seem elementry give'n the knowledge base here. I'm looking at 08 to buy a S4 or maybe RS4.

Thanks for all the input here in helping me in my choice...

 

Yes, in the SCCA Speed World Challenge.

Edit: I should specify, its not backed by the factory. Its independant dealers and teams.
