I have recently ordered an A3 sline in Daytona grey but when I went to test drive the car I saw the sportback sline in Glacier white and I am now thinking about changing. I am 24 and am not sure if the 3 door looks more sporty. I would appreciate your thoughts. I have added comfort pack, SD sat nav, Hill hold, privacy glass as extras and wondered if there was any other extras that I should add as well? Thanks!
