I can claim that one

Yes a great gathering of all classics, there were a couple of other Pagoda's and a 190sl. Had the top down for a journey home in the sun.
Interesting fact. As a test to see if the Congestion Charge cameras pick up our old style number plates I did not register for the charge and have not received a fine.
