Their ebay price is £127 including 48hr Tracked return postage to you. For that you can have gloss, satin or matte leather. Perforated or plain, Alcantara if you want, any stitching etc....
And there is a £50 surcharge on-top of that for your wheel as the 'exchange wheel' if you want to do it that way.
ie: You pay them £177 initially - but get back £50 when you send your old wheel to them.
