A guy from Nelson has converted a Mitsubishi GTO to electric and is looking to make it into a business:... he has some interesting build progress pics on his Facebook https://www.facebook.com/pg/MC3ENG/photos/?ref=page_internal
If someone want to use Facebook to share with faceless "friends", they're idiots, but there's no law against being a corporate lackey to an evil corporation.
But why do kickstart businesses post their blogs to Facebook?
Use something like WordPress free plan for bloggers, and create a web site. There's also free plans from IM Creator, EzyWebs, and Weebly.
I'm definitely not creating a Facebook acount again, just to see a company's blog.
The Toyota HiLux is the most popular used truck in New Zealand. I'm sure that would be a popular conversion, perhaps even get some fleet work.
Ford Ranger actually made an EV truck briefly, in 1998-2002, with awful batteries, so maybe be a good idea to see if that could be improved.
