Oh, I've no doubt that specialist industries will pop up in time - my concern is that parts prone to failure (Batteries/ECU's/Module's/Ancillary's) seem to be all dealer only and quiet extortionate (€2.5k supply & fit for a charging port ECU issue FFS - you'd have an entire ICE engine replaced for that).

Will 3rd party OEM suppliers get onboard and create much cheaper, but equivalent quality parts ? Maybe they do already, I honestly don't know......

There's a reason why even insurance companies are charging major premiums for BEV's - the massive bills that come from even relatively minor prangs.
