Some aircraft may have quite an impact despite being produced in rather small numbers. The Aquila A210/211 series reached 200 airframes last year, but is already fairly widespread among German flight schools and clubs. Many recently qualified German pilots have trained on them. Also, being rather new, most or all of them will see frequent use and thus be more visible than many more traditional types which tend to end up as hangar queens.
A similar effect may apply to the Robin. 1000 airframes might not sound like much, but if most of them are flying in France they’re bound to be a familiar sight there.
Wood and fabric should be maintainable indefinitely, if wood is cleaned and re-glued when the life of the current glue expires. ( More than 70 years in use, and no age problems apparent yet.)

The utility value of a GA aircraft has little to do with design date. Many planes identified as “Hangar Queens” actually fly a lot hours during travel weekdays. One aircraft I know, usually referred to as “hangar queen” actually does 250 hrs per year, as it is being used for travel of two engineers. Some of our club planes are way below that.
Anyway, there are some 270 Stemme S10 flying. Shempp-Hirth built some 4500+ gliders and motor gliders, Alexander Schleicher are at over 9000 gliders and motorgliders. 1480 Glasflügel gliders have been built. Rolladen Schneider built 3000 gliders and DG has built around 2250. 250 Bölkow Phoebus have been built and 2700 Let L-13 Blanik. PZL Bielsko has built 4600 aircraft. 400 Doppelraab have been built and plenty other Vintage gliders.

Cessna in their entire existence (70+ years) have built 152,000 aircraft. Ford sells that many cars every 8 days.
Perhaps so. What proportion of the originally built Cessnas to originally built Fords are still in service!
I suppose I should add:
Thurston Teal: 38 made, 7 still in service
