Most sedan drivers want luxury. Slate achieves their price point by delivering a barebones vehicle. It doesn’t even have a stereo. There’s no market for a barebones sedan.

Historically, pickup trucks did the best in a barebones config. That would be my guess. And as an anecdote, it's the first I've been attracted to. I hate sedans. It can also be configured as an SUV. I will never buy a sedan. There are probably fleet buyers who will like them too. It isn't just a consumer market. There are a ton of municipal work trucks that dont need to be as much truck as they are. Something like a cheap Slate is probably appealing. Parts delivery, etc.
