Amazing you feel that EVs are somehow more maintenance than ICEs. There exist EVs that have never had any manufacturer/dealer input since the day they rolled off the lot.
Tesla/Nio are a bad examples - many EVs were built to be sold and essentially ignored by the manufacturer.
After that EV company goes out of business, how are you going to replace that bespoke {$random_part} that broke? Any Fisker Ocean owners want to chime in?[0]
Do the big companies really have a commitment to parts delivery anymore, or are they following the same trend? Took my friend 9 months to get a part for his C8 Corvette when it got rear ended at 5mph. Tons of other GM owners have been waiting months to nearly a year for many common parts for repairs. Selling parts doesn't make these companies money, so why should they care? As long as they're making enough to sell the new cars first.
* my Ford Focus EV had a very short lead time for parts because it was based on a platform (Focus) shared across many vehicles. Also repair cost was very low for a multi-car accident ($2k).
* Similarly, when common tech is spread across many vehicles (Kia/Hyundai eGMP or GM Ultium) those components are often easier to acquire.
Buying low-volume vehicles or from smaller manufacturers is a recipe for long wait times and expensive repairs. How many Corvettes does GM sell?
Funny thing with Fords is you can pretty much swap parts between models even if they are not officially in the same platform. Lots of overlap. Got a sync unit from a transit for a fiesta, works fine after updating the settings to match the vehicle.
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.
