Not to rain on your parade, but your numbers don't add up. The total with those options is indeed $94,050, but that already includes the $7500 federal tax credit. All base prices listed on Tesla's website already deduct the $7500 tax credit. And California sales tax is at least 7.25% (with most highly populated areas like LA and the Bay Area at 8.75%). So that's around $8000 in sales tax, or an additional $5500 if you get the $2500 CA tax credit. And lets not forget delivery fees of $1000 - $2000. So you're really looking at a final balance of a bit more than $100,000, not the $79,050 you mentioned. But even still, you were somehow expecting $15,000 in tax credits. How so? Even if you didn't realize that the federal tax credit was already factored into the price, that still only accounts for $10,000 in federal and state tax credit.
