I will say a couple of things:
* 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?
