Z2, Z8, and Z4///M Yikes, what's going on?

[Beamer3]

I have been reading various postings on the internet discussing these cars. The Z2 will be on the 1 platform, will thre be an ///M version?

Will there be a new Z4 ///M on the new product line?

Also, I saw 4 - Z8's yesterday for the first time in a local dealer showroom (selling for over $100k) and thought it is a rather nice looking car. Some of my readings were very old postings talking about the coming of a new Z8. Is one planned for production? What can anyone tell me about this and also the history of the original Z8?

This is all very confusing.

Thanks, George
