Omegas are currently in the 'not old enough or LotusCarlton-y enough' category. Anything older, Carltons, Sennys, Monzas theres plenty of. (
lots of Monzas this year! I swear they didn't make that many!) and not new enough either. There were more Omegas a few years ago, when they were still relatively modern cars, and therefore plentiful.
But give it a couple more years and there'll be those who are investing in bodywork now, putting their cars back to standard factory etc, and rightly proud and wanting to show theirs off. As you say, not many Omegas now, but their time will come. Carltons were on the doldrums a few years back when I started going. One rusty GSi, a couple of estates etc but they weren't
show cars, they were just the old workhorses that were bringing club stuff/family/caravan and ten dogs etc.
Happy that at Saturday Billing mine was the oldest Omega there
