Thanks all, for your idea's and suggestions....
I've put the order in as per my original spec.
Reasons being quite simple in the end....
I was set on the M Sport - I just like the sport look. (And I am more of a style over performance sort of guy)
I was set on the 18" Alloys - I just think they set it off a treat (and I'm not overly keen on the 17" ones)
My budget didn't stretch to a 320D M Sport.
The good news is that there is the exact spec car in a dealer showroom in Scotland that will be winging it's way to the dealer in Surrey and then back up to me in the midlands before the end of the month !!!
Happy days !
If it arrives in time I will try to get to your meet - it's not a million miles from me.
P.S. I would have had a 320si in a shot if it didn't have such poor co2 figures. It would have cost me well over a grand a year out my pocket in extra tax!
