you can get alcnatara wheels on eBay. do a search, I bought one a few years back but they come without a vital component for th ehorm which meant I had to buy a TT wheel, pull the horm ring out, refit it to the alcantara one. then buy an airbag!
wheel and bag probably cost £3-400 all in
Sold my original Sline wheel, the TT wheel and the original airbag for close to £300 all in.
£100 for an alcantara wheel and airbag? bargain
