Jerome, the VP of sales just to replied to my email:
"Thank you for your note and your order of a Model S.
We will be introducing additional wheels for the P85D (although we do recommend the 21”). Jessica, whom I have copied on this message, is based in Rocklin and will be able to help you with the modifications."
Wow Tesla really can't get their communication right. This contradicts what I was told last night by someone in sales in Fremont. I also had an exchange with Jerome about this last week. No mention of other wheel options at that point, just the alternate interior color options. This must be a very recent change based on customer feedback. Good! I told him about my experience with the 21's, and suggested that if they offered a turbine look 19" wheel in grey that I thought it would sell.
