I've a spare CDV (came from Zeckhausen in the U.S) suitable for the Z4M/E46 M3, this is new/never used as I inadvertently ended up with 2 for my Z4M ... one already fitted to the car, this one for sale.
I think the exchange rate means that the actual CDV works out to be about 18GBP and IIRC the postage should be about the same, effectively doubling the price.
