Agreed; I suspect the reason why the VW has been targeted by EV makers is largely because the tuner/enthusiast crowd is quite large, and also it's an extremely well understood/documented platform. I haven't seen the EV West stuff up close in person yet, but it looks like as a platform to develop a set of standard equipment for other cars, the VW is a good initial choice for those reasons.

I have a similarly size/weight prewar french car, and when the engine finally gives out, will probably pull out the petrol engine and swap in a VW kit, but with a custom bell housing adapter. A 70-100hp electric motor meant for a VW is not a lot of power, but can provide enough low end torque to keep the car driving in modern traffic for 100-130 miles, which is probably enough for the use classic cars get.
