Congrats man! To date, I haven't entered any "awarded" car shows with the '6.
I entered in one for *****-and-gigs a year ago with the Limited, and the judges were confused whether to list it as a domestic or a euro...
Tried domestic first, then they wanted a mod list. So, I submitted one that included Mercedes-Benz, AMG, Eurocharged, Startech GmbH, Ansa and got the deer-in-headlights look. They switched me to Euro, and I was ultimately beaten by a mid-60's Beetle (owned by my uncle-in-law).
Graded car shows aren't normally my thing, but I may give one a whirl eventually.
