Hello, I want to buy Audi A4 B9 combi, but I have few questions. I m sure I want it in S line version and I m really interest in "autonom" riding with lane asssit, trafic jam but not all version have it becasue I want it buy it from market. So it is then possible to somehow code or mount it ? and same questions is for ambient lighting there will be probably need mount some lights. Then soundsystem Bang and Olufsen is better than some aftermarket system ? do you have any recomenadation to aftermaket soundsystem ?
