Tesla is the iPhone of Vehicles. If you own an iPhone, you'll want to own a Tesla
Nowadays there are very few cars on the road that when you see one, your heart misses a bit. Tesla S is just a beautifully designed vehicle, with slick lines and an European look to it, and that's only from the outside. The inside feels like a jet cockpit with everything you'll ever need plus more. Musk is a genius and those who doubt him will find out that you should never bet against smart, talented, rich and successful geniuses.
I kind of agree with where you're going as Tesla is amazing. With that said, your analogy is pretty misleading. iPhones are way outdated and are getting owned by Samsung right now. They haven't released anything innovative or game changing since the first one. So in that aspect, I don't get your analogy.
