Corvettes are niche cars, with only tens of thousands sold a year. Plus, I don't know when your friend got in that fender bender, but post-Covid supply chain issues meant that anybody in any newer car (with lots of electronics) who got in an accident in the past few years waited a while for parts.
Last week, I finally got my second key fob which was absent because of a chip shortage. So even until last year, we were still seeing the effects of the supply chain disruption.
