That is very true...
if possible, I'd better move to somewhere closer to other dealershops for my X5's future. ha...
fortunately, there is another one near my house(30min drive. it's not that bad) and if needed I'll go there. 30min's much more worth it rather than letting them put the screw on my X.
anyway, thanks guys...
