SA is for Sales Advisor. That’s the terminology Tesla decided to use. The same way Walmart uses Associate and Best Buy uses Agent.
DA is for Delivery Advisor. DC is for Delivery Center. SC could either be Supercharger or Service Center. And your local Sales Advisor is correct. Tesla recently did a structure change which resulted in the Stealth now costing just the same as Performance. It used to be $2k more than AWD. Unlucky future buyers.
