Hi, I have an A Class 2006 reg and have just fitted the mercedes roof bars that allow for the sliding sun roof. Also wanted the Medium roof top box as it seems to be the best size for the car, to be told that they don;t make it any more... the only sizes available now are: 220 x 60 x 41 220 x 80 x 40 Having looked at the size of the 220, the length of the box appears to be out of proportion to the car. Even if the box is placed as far back as the roof arial, I suspect the front still over hangs 80cm past the front bars, ending near the end of the dash board. Has anyone seen similar sized boxes on the A - Class. Would like to see it and get your experience prior to deciding on what to buy. Let me know, thanks, David.
