I think we know what it isn't, and that's an Esprit. A test mule would have some obvious camouflage and would look like a new design, which doesn't apply to this. It certainly doesn't look like anything other than an Evora, so I'm not sure why anyone would think this is an Esprit.I don't know what this is either, but haven't we all had this discussion before about what a test mule is? It's not supposed to look different. It's all about what's underneath, so the widened track is suggestive at least.
Or maybe it's just spacers on a car somebody's trying to bring back to life.
