Maybe they didn't understand and quoted him the EAP post-purchase price?
FYI, in the Tesla owner portal under Shop / Autopilot Upgrades... I am seeing the option to pre-pay $5k for FSD. Just bought and picked up my car the first week of Jan 2019.
Full Self Driving Capability
Adding this option today means you will be one of the first to experience full self-driving when it becomes available in the future.
This functionality is dependent upon extensive software validation and regulatory approval. It is not possible to know exactly when it will be available, as this is highly dependent on local regulatory approval, which may vary widely by jurisdiction.
Note: Enhanced Autopilot is required for the purchase of Full Self Driving Capability.
Buy for $5,000
...I first went into the Service Center...
...I’d need to go to sales
...check with his manager ...
the sales manager sent me back to service.
...service rep then quoted me 7k....
The website worked flawlessly at 5k,
That's exactly backward.
EAP is already feature-complete, other than slight upgrade to summon and removing the "approval" for lane changes.
Further we know the HW is already near its limits for EAP. They'll likely still improve it as much as they can within those limits of course.
Only FSD needs the better hardware, Elon has specifically told us this, which only makes sense if that's where all new driver assist features beyond the EAP feature list will be going.
