I have no concerns re: actual vs advertised range. None of my regular commutes, or occasional weekend errands, get anywhere near even 150-160 miles, and I've already got the level 2 charger from the Volt installed in the garage. And for any family outing that might exceed the car's range, we've still got the missus' gas-burning SUV (vw Atlas). I never had serious concerns re: build quality, either, given that it's designed by a mature car company, and built by Magna Steyr (spelling?). Software 'glitches' are understandable, and fixable. I just fear a major software snafu that might 'brick' the car, and leave me unable to get to/from work.
As an aside, my dealer mentioned almost in passing that when the car needs servicing, they will pick it up from my home, leave me a loaner, service the car, and return it when finished. When I speak to Mr SalesGuy again, I'm most certainly going to double check this, since it's kind of a big deal. The dealership, which is the one closest to me, is a roughly 45 minute drive. Has anyone heard about this? If I recall, i think Mr SalesGuy implied that the home pick up/drop off is part of the Jaguar Elite-Care warranty. If that truly is the case, it makes the prospect of owning a potentially 'buggy' vehicle significantly more palatable.
