Noticed there were several new A4's up at M.A.G. this morning. (more-->)
 

A couple of 1.8T's and 3.0's. Sitting beside them were some A6's. Not much difference between the new A4 and the A6. The A6 was just a smidge wider, maybe due to slightly larger fender flares. And the lower skirts are body colored on the A6. From the rear the lights are the give away, besides the badging :-)
Something I wasn't aware of: Both the 1.8T and the 3.0 have dual exhaust. I thought just the 3.0 was supposed to have that.
All of the new A4's at the dealership were Tip's, no manual 6-speed in sight. I was told one was around back having a mirror motor replaced (already?) but I never got a look. Also no cars with the sport package.
Not to thrilled with the design of the car. I waited until I had a firsthand look at one before passing judgement. The results: I'll be holding onto my current A4 and hoping the new S4 is more visually appealing. I reuse to by a car that from 50yds looks like a Passat or A6. Nothing wrong with either car, I just think VW/Audi should have a bit more distinction betweens it's models.
Opinion posted, running away now.
