I got my first Model S90D in August 2015 right after a 10% increase in price and I knew I could have gotten an inventory car without the price increase but didn't need the P85D version. I signed the contract and agreed on the price.
In March of 2017, my wife got one of the first X100D and I knew we were paying a premium on the SUV. Total cost with all options before taxes was $166K. Today, a X P100D with same config is $140K.
Finally, in Sept 2018 I traded in my S90D for a P3D+ and again paid $103K for a vehicle that cost $85K today. Do I feel cheated or jaded? A little, but I agreed on the price at that time and that’s what I paid for.
After being a Tesla owner for 3.5 years, I don’t regret owning these Teslas even with the 3’s quality control issues that I had part of my 3 repainted and other issues fixed in a timely manner (one month after delivery they had my 3 for a week to fix the paint issues).
I have friends who keep saying they will wait for this or wait for that to come out or they are waiting for the US federal incentive to decrease again so that Tesla can do another price adjustment is ridiculous. If you can afford to get a 3 now I advise you to just get it and enjoy it...otherwise just get a Bolt, Kona, Leaf or another electric car that doesn’t adjust there prices like a yoyo and is in your budget.
