That's growing pains though. Give it a few years and there should be greater parts availability and independent electric car repair shops.
> But anecdotally, after many many years of disappointing experiences with independent repair shops, when I could finally afford repairs at the dealer, I was no longer disappointed.
There are a lot of bad mechanics out there. The trouble is as many of them work for the dealerships as not, so it's not much of a filter in general. Even if the quality at dealerships is slightly higher, the possibility of going to an independent shop is the only thing keeping their prices in check. Or their service quality for that matter.
