OP,
Looking back at your original post, it looks like the real discount you got was not $5,660, but it was really $8,660.
The LR RWD does not include Autopilot. The system initially generated some quotes saying it did, and others fought hard to get Tesla to honor the deal but they were told they would not. So everyone else had to pay $3K to get AP on a LR RWD model. Your quote shows it as being included, so they only charged you $5,000 for FSD when it should have been $3K (AP) + $5K (FSD). That turned out to be an even better deal than you may have realized.
Oh I definitely realized
I was actually reluctant to even post this to begin with because of the incredible overall "deal". It was just perfect timing of when all the price changes and adjustments with AP were happening.
