Even if Chevy branded their e-van as the Astro. I'm not sure how much it would share with the 1st and 2nd gen vans in terms of simplicity and maintenance. I want a 90's shit box not a fancy pants electrobile.
They'd probably go with a lower CG and a lower floor design than our Astros. Of course the battery below the floor might solve the CG issue). I think VW sells a van in Europe that looks a lot like an Astro, so I'm sure GM could design a current van that reflects Astro styling.
It's OK looking for a new vehicle (the styling bar is pretty low these days IMO,) but I don't want an electric van. An electric car, maybe if my next job is "OTR," but not a van to haul the family--at least not until there are a WHOLE LOT more charging stations.
