Could be about right I would think - it wasn't that old as I remember it from a five or six year old's view, and of course back then, didn't look 'vintage', especially as there were far, far fewer cars on the road in the UK. We were one of the few families in our 'street' (it was a large, horse-shoe shaped drive of around maybe 100 or 150 semi-detached houses) who actually owned a car.
I remember my Mum had fitted curtains to the rear windows, so that on the return journey from, say, the Northumberland coast in the evening, after a long day on the beach, which, in those days, took around an hour and a half via narrow country lanes, me and my older sister could lie down on the rear bench seat and go to sleep !
I'd love to be able to see one of those vehicles now, and if I had the space, and the spare dosh to run and maintain it, I'd ,like to own one too !
