Yes, the car I am going to order will be a US spec one. We can order german cars, and the like from special dealers off base (not a typical Audi or BMW dealer). Unfortunately, even those dealers are totally clueless when it comes to the A5/S5 audis. They never heard of the side assist, or drive select, etc. I actually have more info bec of these forums than the actual dealer (no surprise there).
So 15 MPG for the S5 sounds about right.. its about the same as the ford mustang ppl in the states are going crazy for (I don't care for it really, the interior is too cheap and plastic).
Height adjustable suspension? See, I didnt know that existed. Is that like the drive select, or is that something totally different. Most of the options that can be ordered in germany or the UK, still aren't available for the US spec ones (even though I am ordering in Germany). The only difference from buying here, instead of in the states, is that we get a bit of a discount for being in the military, but shipping/port handling fees are included in the price.
You guys are making it harder for me LOL. I don't know about an S-line or S5 being a daily driver.. prob be a weekend driver or special day kind of driver. If I could get the MMI controls by the shifter without getting the Nav, I wouldn't get the NAV.. but I like the controls there. I never owned a NEW v8 before, and I dunno if I could give up the S5 for a 3.0 TDI S-line if it ever comes to the states.
