This is what I have real issue with. Without a contract, you might as well be buying magic beans.
This isn't marketing / PR / comms, but simple sale of goods.
If this was Ford offering you free Shell gas for life, you can bet it would be backed up with a terms and conditions at point of sale.
Why should we let Tesla off this level of basic admin? They are not a charity!
There are no terms, and the only recourse (like the Ranger service) if things change is a very unpleasant journey through the courts
Saying all that I am making some progress, by being explicit and deliberate in my questions, and I am getting concrete answers. But it is like trying to nail jello to a wall.
So far I have confirmed it is as advertised at launch "free and will always be". My final point of contention, is what defines lifetime, and if this is transferable on sale of the vehicle.
By getting these in writing if there is ever a material change in policy I have protected myself as I can use the UK's "sale of goods act" with concrete documentary proof, and run it through our small claims court to recoup my fee.
That is all I want, both purchaser and vendor being clear on what the transaction is!
