That's really depends on what you want from a car, doesn't it? For me, all personal and IMHO, of course, multi-month repairs over trivial issues, having to plan your trips around charger stations, and, yes, lack of luxuries that are by today not out of place even in in midrange cars costing less than half the price of a model S... that's not minor issues.

And of course I am too old and cynical, and want my stick shift back, but the driving experience in Model S was very much blah. That's one of those things that you can do well only if you know how to build cars, not computers on wheels.

As for ownership experience, maybe it is that bad with BMW, although I doubt it, but I've never had any problems with Audi, and it has been far more pleasant than what I've heard of Tesla...
