This seems to be a major issue with some to the extent that it seems to be clouding the strong points of the car overall.
I have the same build as Dusty and I haven't noticed any significant problem. With a boot liner any small dribble that enters the boot is easy to mop up but I haven't noticed any worth the effort to date. (I didn't realise it rained a lot in Vic
)
If the fix was offered I would have to seriously consider if I wanted it as I believe that it involves refitting the glass something I can do without.
Mine goes for it's 15000k service today with the issues being a minor upholstery issue with the drivers seat, surface damage to the front sensor push button and minor surface rust on boot entry (from a slightly misaligned hatch) I have also asked to have the AC checked although I haven't found this to be a major issue as the car is white and no doubt doesn't heat up like darker colours.
