First things first...
I know there £500 odd a wheel new(I have them myself) lol
And yes in a idea world you cud get more but it's a buyers market out there and everyone's after a bargain, including ourselves..
I bought mine for £650 without tyres and they were brand new...I troll fleebay regularly and the shadows are becoming more and more available...
When I sold the Seattles which were without tyres I first started it at £300 but after a couple of days no interest so lowered it to 99p to hopefully get some bidders and walaaaaa they sold for just under £800..
But honestly mkviken stick it on eBay with a reserve and see how you go...
