And how to get them into the UK. Shame really. I’m not at all keen on chopping up a Z3 to make a Cobra or Ferrari. But chopping up a Z4 to make a Z8 really appeals to me.So here we are 2 years later, and have you caught up? Me and our new neighbour were talking about this same subject over dinner last night. I have a relatively low mileage E85 Z4 but I don't know if these kits are still produced.
