'82 Coupe, rear wheels askew

[TWFAUST at aol.com]

Well, I was followed home by another Audi, this one an '82 Coupe. This was a 
lesson in buying a car in the snow. I sent it out to be cleaned and buffed. 
The detailer pointed out to me that that the rear wheels are both moved over 
about 2" to the driver's side. He doesn't have a lift, so looking under I see 
what looks like a sway bar hanging down. It appears to be round, but could this 
be the Panhard bar? Are there any other likely causes for the wheels to shift 
over?
