And there it is.

Back in days of yore, when tootling along the highways and byways, we'd find ourselves in rather undernourished roads, where two cars would have to be exceedingly careful to pass one another.
A common utterance in those carefree days was ... 
"All we need to meet now is a foot high sports-car." And there it is.
We couldn't decide if that was an as supplied Rag top, or an owner's lash-up.
We were en route to Houghton Hall where the "extra" was the best of the unusually few I shot that day.
I have a kinda felling that it would not have obliged by waiting for another shot with it in focus to stack?
