@DaveT I'm so thrilled to read your review of the test drive and to hear that you're finally taking delivery (or probably have by now, and are too busy driving it to be posting here).
I love reading your posts, and I too invested in the stock after learning about the Model S and researching Tesla's plans to build superchargers. Back then (2013), the S ramp was just beginning, and there were something like a half dozen supercharger stations mostly in California. There wouldn't be any in Canada for quite some time and I had not yet test driven the car. But I read a ton (mostly on this site) and started to realize that if Tesla came anywhere close to the dream of a lower cost car (now Model 3), the stock was a no brainer, and was not pricing any of that success in.
At the time I also had no frikkin' CLUE about autonomous driving (I literally thought it was a joke when Elon started to tweet about it), and I had no idea they'd expand into the energy business or build GigaFactories to lower production cost.
My own test drive and purchase (S85) came about a year later. I'm very glad I saw the light (or electrons?) and invested in the stock when I did.
Keep in mind I'm writing this in Ontario, Canada when we have been experiencing temperatures of -20C for a couple of weeks. It's insanely cold. Yes, range is affected, but Tesla (as a winter car) is unbelievably awesome. People are plugging in their diesel trucks / cars just to ensure they can start them. When people in this climate realize what an EV truck can do, they'll buy. My town is all about pickup trucks.
Growth still ahead is huge. YUGE.
Model 3 ramp, Model Y, pickup, semi, energy business, autonomy (100% gross margin for software upgrades) ... I'm pretty excited for the next 10 years.
