Hi Martin.....welcome to the Forum
AC or not, I'm sure the Zed is a superb car especially as it has a 3.0 litre lump in it.
I assume this is the badge you are referring to?
You can get aftermarket ones through BMW suppliers, not sure of costs though.
Feel free to post up some photos if you want, would love to see it
Good to have you onboard
Cheers, Trevor
