Well, not wanting to start a fight - don't wanna roll around the floor about it

Looking at your rattle list and then your last statement " only used for b road blasts",
ANY vehicle will need after a time of hard use some amount of tightening up, all those panels with all the stuff bolted to this and tied to that - under the effect of G can't help but move- after a time.
A true monocoque hull of a sailing yacht, carbon and epoxy with lateral re-inforced stiffeners and moulded in bulkheads will in time even with designed use flex, that's a monocoque and our cars are boxes stuck on frames with more boxes and frames with various materials attached/covering/bonded to...all that heaving around bends at any speed, things will pull away microscopically at first but any movement builds upon itself, with every harsh bend your dash and console are getting pushed pulled squeezed all at once...
I drove a polo like a go kart, not bullish but fun. New bushes, wishbones, tyres etc etc, the dash eventually started creaking, the plastic centre con. gave its plasticky creak at roundabouts, it was obvious what was going on.
My next polo, (pictured in me danke golfsburg note) as a result of lesson learned, has been driven a bit more sensibly and it's showing no interior issues. Build is vorspung durk !
In me vi, I'm gonna cherish it for as long as poss.
