Very sad to hear, a lovely chap who like Ewan, also sold me my first Maserati - my 3200AC. He and Penny were a great team, I remember the tale of David popping Penny in the boot of a 3200 to look for a water leak and she came out smiling - and found the leak!
I also remember my first test drive with him - wow, I'm not sure I ever recovered from that and those who sat alongside him will know what I mean!
A sad loss for sure
