About a month ago Tesla announced that the US Bank Lease would include a Happiness Guarantee. Elon posted a new blog post mostly about the incentives that Tesla is getting from Nevada for the Gigafactory. But in it he said the following:
This implies that the Happiness Guarantee essentially applies to buyers. Given the way Tesla has treated me with my own trade of my September 2014 S85 that I'm replacing with a S85D, I'm not surprised by this. They've done a lot to build long term trust with me.
At Tesla, we believe in doing deals where both parties benefit, and, when there is an asymmetry or underperformance on our part, interpreting that in the other party’s favor. This is true for big deals like the Gigafactory and for everyday transactions. For example, if you buy or lease our car and don’t like it (within a reasonable amount of time), you can automatically give it back, accounting only for usage and damage. Tesla will absorb loss of the new car premium when reselling it as a used vehicle.
Our goal in doing so is to build long-term trust. If people know that we will not take advantage of them and aspire to fairness, even at our own expense, then they are much more likely to want to work with us in the future.
