A lot are buying on name and image only, only another like cred car would be OK to them.
We will see how that plays out over time.
As for Bolt sales I think the more attention to EVs , the more EV sales there will be across the spectrum.
The M3 validates the Bolt and Leaf, just as the Bolt validates the Volt.
All ships will rise.
Given the type of person a M3 appeals to, a very long wait could result in some strange standoffish smugness between those with M3, those who want M3 and those who don't care.
I've already witnessed flame matches of a certain type of fanboy who joins a model specific Facebook page or Forum
And starts mentioning solutions to everyone's problem there being a M3
Many times it's off topic and rises to them being banned, noticed this tendency on a Corvette forum the Volt Facebook page and even on Prius related places.
I'm still uncertain what a Tesla has to do with how to clean the intake on a direct injection car
Or how a Tesla would solve a broke guys $1500 used car related repairs,
but apparently there is a subset of people everywhere sticking it to someone spouting their battle cry Tesla can on basically every remotely car related forum.
But it's appreciated just as much as telling someone they dropped their pencil.
It's almost like car forums have been made into gamer rating discussion forums
Or worse YouTube reaction videos.
