Might be worth seeing you could get them on eBay in Germany? STD GTI over there comes with 17s so could be a good market? Or eBay here. Lots of Parkerists on here 
Note that if you're selling them in Germany, these wheels are actually called Milton Keynes (yes, seriously, check the vw Germany website - I presume they prefer new towns to the butler in Thunderbirds in Germany) so you might want to also include that in the listing.
