Got a flash and a wave from an "old boy" (I am only 71) in an MG Midget and another in a MX5 yesterday, there doesnt seem to be many Zeds around Northumberland!
With me living in Oxford, it is typically rare to see "interesting" or "drivers" cars around here, yet I regularly come across 3 other Z4MR's!
My folks and I are going to be moving away from Oxford, to one of the the surrounding counties/village, as the house market where we live is crazy as we're right be the 3 big university hospitals. So you have high demand for housing here and because our house is a 4 bed detached, people are willing to offer silly money for it. Typically my folks will get one or two letters hand delivered by people who want to buy the house from my folks. You may be thinking "get to the point Felix" , with us moving to a place where we can have a nice big garage, Poppa and I are going to get a kinda project car (nothing too major, as it's incredibly painful for me to bend forward even a small amount and I struggle to sit on chairs for any length of time, unless they are good quality car seats, that support my damaged sections of spine really well) but use it as a father/son activity. We will often go to meets and shows together and being away from Oxford city, we won't have to put up with the utter horrific Oxford road and traffic system.
It is quite possible that my Z4MR will morph into a Z4MC, as even my dad has fallen under the Z4M's spell!
