Hey Diecast,
1) Pricing and ordering can be found here

2) The V1 which had partial leather is no longer available. You might get lucky in the for sale section if someone has one for sale. The V2 wheel is covered in Alcantara.
Jon@bmwpartspros.com can help you out if you want to order a wheel.
Hope that helps!
