Hi, Today I have put down a deposit on a new S3 Sportback, with everything I wanted bar B&O. However it is in a dealers, available for 1st March and a relatively cracking deal on the finance. Essentially: Panther Black S-Tronic Tech + Comfort Sports Seats F37 Wheels Park + But no B&O. So the question is, what are the thoughts on the standard sound system? Is the B&O worth it (reading mixed reviews) and equally, can I retrofit through my dealer? If I chose to forgo the car and order, I'd be May / June.. Someone I cannot do as my current car finishes its term next month.. Any thoughts would be gratefully appreciated.
