I ordered my Model Y early October 1st and was waiting to actually own it before upgrading to FSD. I wanted to make sure I liked the car first and wanted to charge the FSD upgrade to my credit card. Of course it took a couple of weeks to get here, and I didn't take delivery until last week. Well now FSD costs $2k more. The price of FSD suddenly increased by 25% while I was waiting for delivery. Who should I talk to to see if they could still honor the original $8k pricing before I buy the upgrade?
