Thanks guys, I'm pleased that you found the write-up interesting. Good point about the mirror Martyn, I hadn't thought of that though I guess I'll be driving it mainly on my own. For instance for the LMC, I'm taking the 3W and Head Office is driving over the Aero SuperSport with the luggage!

I had been thinking of fitting a mirror
like this. However, this one could get over the shoulder height problem, being an adjustable one based on a
Jaguar model. The big downside to this could be the issue of vibration that Martyn mentioned.
I think that I won't order any mirror until I've done a bit more research, once we are back from the Geneva Motorshow/France.
