What is the Optimal vs Less than Optimal time to buy? I see a lot of the forums threads get clogged with this discussion about people who get caught up in the ever changing quarterly cycle and I wanted make a place toshare these thoughts along with my own experience. My observation: A pattern has emerged in 2017 from what I can see, an early quarter change followed by a mid quarter change to push sales. My experience: I can only relate to my experience and the stories I've seen on this forum and I've been on both sides of the coin, the optimal and less than optimal time to buy. I bought my Model S P100D late Dec 2016 build at an optimal time. I got leather, ventilated seats, plus everything that is available today at thousands less. I bought my wife's Model X100D at a less than optimal time. Early April 2017 build. Doesn't have dual chargers or performance upgrade that the cars have in early Q3. Worse yet I took delivery at end of Q2 making it closer to the performance changes. My Thoughts: From my perspective is there is two ways to think about it. 1. I got ventilated seats and saved like $10k, Ive got 22" silver turbines, tan leather and those aren't available. Basically appreciate what you've got that those who are buying now don't have. And/Or 2. Your vegan or non vegan X 75D is faster then my non vegan X100D and if I would have only waited 3 weeks I could have had a faster car. If I would have waited 4 weeks I could have had cream interior with sub zero included in the premium package and dual chargers. Have regrets about the time of purchase. Bought my Model S P100D at an optimal time (dare I say perfect time), bought my Model X 100D at a less optimal time. But I really feel lucky to own 2 Teslas. We enjoy both and they are both phenomenal cars. I see P85+ cars and those are awesome, I see P85s those are awesome, I see P85Ds those are awesome, Model S 85s are awesome, I see X60Ds those are cool! I have an appreciation for software locked 60Ds those are cool cars. To the community: New buyers and seasoned owners look to this forum for answers, see an optimal time voice it here. See a less than optimal time, might be worth noting here.
