I'm wondering what kind of mileage you get in stop-and-go LA traffic- the kind where you average 10-20 mph. I get ~12 MPG in my tip S4 avant. Even if I try to drive very conservatively, it only makes about 1 mpg difference. I'm interested in both the manual and auto A5, since the auto apparently gets better mileage according to fueleconomy.gov. If you live in another city with similarly awful traffic, feel free to chime in.
