From what I have seen of the MK6 its more for a facelift MK5 to be honest. And with the 'cost cutting' redesign for the MK6 us MK5 owners could still own the best built golf (in my opinion) for a while yet. Time will tell I guess.
I dont think the build quality on the mk5 is anything special if anything it's probably worse than vauxhall/ford
It's weird considering they've just launched the mk5 golf in the states and the mk6 is out in 2008 supposedly. Does that means wolfsburg will be making 2 generations of Golf
