In addition to mine SIG 791, another one of the few SIGs signed at the factory for customer delivery was Andrew Wolfe's SIG 440
So, What exactly is the value of a Signature Model S? Oddly he did not ask or even know it was signed until he saw it on the visor. Mistake? Easter Egg by Elon?
The Sig's signed after the fact will not be worth near as much as "the real SIGS."
I have emails before and after delivery from the executive based at Fremont who was in charge of all deliveries in the Northwest region. The Tesla Service Center manager and my DS saw the car with Elon's signature
before delivery to my home. This was part of the "Tesla Personal Delivery" program by George B "We will deliver your car wherever you like: your home, your office, your friend’s house, your hotel on vacation, or anywhere else
that makes you smile." It's time to build your Model S
When I saw this, I called my delivery specialist and said if you want to
make me smile have Elon Musk autograph my car. What good is having a "Signature" Performance Model S that is not actually signed by Elon!!!! From one of my email documents:
"I'm writing to confirm that your Signature Model S did receive a signature from Elon Musk on the sunvisor. When we spoke about at that time (November 2012), I did have it arranged to be signed by Elon via working with his assistants at the time.
I worked at the Fremont factory while managing our entire delivery team there (and the entire Northwest region at the time). During my time, we only had a small handful of "signature requests" for Elon that we executed on, yours being one. We never advertised it and shortly after this started declining it on behalf of Elon due to time restraints."
