Yeah I could always put in an after-market speaker system down the road that'll probably be just as good but not cost as much. So that's not my biggest concern I'm just kind of curious what the differences with and without the sport suspension if it's really that big of a difference. It seems to be difficult to find a used A7 with the Innovation package, driver's assistance package, LED lights, and the sport suspension package in my price range

I had a 2012 A7 TFSI, drove it for 3 years. Traded it for a 2015 A7 TDI

The TDI is much more economical (Diesel fuel being cheaper than gasoline), gets better mileage (I get on the average 850 km from a full tank in city driving, just over 1000 km on the highway). That is 1/3 more than I was getting driving the TSFI.

The car is much more powerful, better acceleration, higher torque.

I find it interesting that only the guys that have Diesel engines are chiming in . Nothing from anybody with the supercharged version

I have driven all three, TDI, V6 Supercharged and the V8 TT. The TDI was great and would have won if it was between that and the V6, but I went with the V8TT in the S7.

Thanks for the information friend!
