Morgan has one also...cool...
I think I know of one they missed
DOn't know the name of it but it had Michael Buble and Krista Allen in it. She crashes her white Z3. <A HREF="http://www.racefanstv.com/index.cfm?template=magazine&mti=15">Read "Through The Esses" on RaceFansTV.com</A>
AH! Wasn't on the M Roadster list...now I see it!
Not quite the same thing, but...
A BMW roadster is central to the plot of the 1999 novel X-Files: Skin. Sadly, it is the total destruction of the roadster in a massive highway pile-up accident that begins the adventure for Mulder and Scully. Never called a Z3, but almost certainly had to be what the author was thinking about.
