Thinking of converting from the BMW scene to Audi. I found a car advertised as a 2006 A4 3.0 cab. Looking at the model information on this site, the 3.0 wasn't offered in 2006. This is the link to the car. Any insight from experienced Audi enthusiasts would be appreciated. Thanks.

I don't think the ad is wrong, Audi went from B6 model(1.8t and 3.0) to B7 model (2.0t and 3.2) in mid 2005. But, the cab models stayed in the B6 form into 2006, and wasn't updated to the B7 powertrain and exterior until mid-2006, so the B7 cabs were available as the 2007 onward.
