Trekking my usual journey this morning I caught up with a red Mk1 this morning heading up the M42 just after J4 and followed him up to just passed J7. After that I overtook him but he caught up again as I was splitting off at J9. I looked across smiled and nodded but not sure if I got a nod back or just confusion
Quick look I'm sure I spotted a Roll Bar through the rear window and if I'm right I think it had a Mk2 bootlid. Might be completely wrong but looked a curvier edge than I remember for Mk1s.
