My point was that waiting to put in a reservation delays getting a Model 3, as right now 250000 reservations are in, and that will likely mean the last on the queue of reservations is looking at delivery well into 2019, if reservations hit one million (a distinct possibility), then forget "walking up and buying one" until well past 2020. I personally predicted 100,000 reservations in the first 24 hours over a year ago, and was happy to be wrong!
I already own a Tesla S, so have 100% faith in the company and technology. After almost 80000 km on our car, it is one amazingly powerful and smooth ride, and charges to 96% of original range, over 410 km "rated". Tesla is a brilliant company with a significant lead on it's competition!
