Nice

Hopefully you will have lots of fun driving it

I am biassed - but this is by far the most beautiful car BMW ever made

(Z8 comes close)
A few tips:
- The M is surprisingly easy to unsettle if pushed - keep DSC on if you are not serious. You don't want to do unscheduled 270 degree turns
- There is a Clutch Delay Valve that regulates clutch pressure (you can only dump the clutch so fast) - I am sure BMW has it there for a good reason, so mine is still in - but - one of the most common mods is to 'delete it' - the various Z forums should be overflowing with DIY's.
