The full Oettinger Body Kit for the MKV (full replacement front bumper/grill/foglight mounts, carbon fibre front lip, plus more substantial side skirts and a replacement rear valance) cost $4k. It had to come from Germany (via HP in QLD and European Autotech at Mona Vale).
Painting and fitting cost around $800 (same as VW, except there is a lot less painting and fitting work to be done!).
So the VW kit is cheaper, but then it's just 'tack ons' rather than complete replacement parts, so it's a lot less substantial. I'd rather pay the $4.8k than the $3.5k :)
Though they haven't got one for the MK6 yet...
