In my experience, MS6 owners are generally (generally, I know I haven't met all of them and there are exceptions) idiots. They look for any reason to race now that they can afford something cheap and fast, and when they lose they are laaaaame. I'm not saying you'll be associated with these guys, I'm just saying that the community you'll be excited to join may disappoint.
I think it was Motor Trend that did a comparison of Mid-size AWD turbo 4-doors. Among others were the MS6, the LGT Spec-B, and the A4 2.0T. The 2.0T won handily, but the LGT came in a close second. It totally outperformed the MS6. The MS6 forum (probably the one linked earlier this thread) erupted with cries of foul play, claiming "the MT guys probably didn't ice down the IC on the 6 before it ran its lap, its bullshit that the LGT won!"
