I have been to both (and the 'Radio show') anyone remember that? I think most of the cars at Earls Court were BMC and Ford and a few Rootes Group as well, can't really remember in much detail.
When it went to Birmingham I was mainly interested in the CX, I remember telling the rep that I was going to have one of those - in about 10 years time
and I did, fantastic car, ran them for about 10 years. As soon as I got one I stopped going.
My main interest was diesel engines, I ran my first one in 1959, I used to spend most of my time at the Perkins stand, I still have some literature obtained there including a fully illustrated brochure on an engine they never made, the 'Iceberg' it was called, it was a diesel version of the three litre rover V8. I think its failure was at least partly political.
I also spotted a rather humorous mistake in the Hains CX manual which I brought to their attention and they subsequently corrected.
My word that was a long time ago .....
