Well, since you live in L.A. area, you can widen your net to anywhere in Calif to find one, IF you don't mind "a road trip". A one-time trip to the Bay Area for pickup would probably require two DCFC stops (if you left with a full charge). A one-way trip to the area should cost under $150.
So this is a two-prong attack.
Reach out to San Jose area dealers (Dublin Chevy, Fremont Chevy, Capital San Jose, ...) all of them. They all have LOTS of cars sitting on the the lot.
Reach out to all of them via email, and say something like:
- I am planning on buying a Bolt this year
- This is what I want (details of color and packages)
- what can you offer me (prices, features, and colors)?
THEN, after you get any offers you like, re-contact those and tell them that if all turns out well, that you will be flying up from LA to pick up the car, so the vehicle MUST be ready on the date of pickup, and the battery must be full. And just before heading up there, make sure to get something in writing (email or fax) with the car info, VIN number, and that if they can't deliver the car to you at the agreed-upon price (?before a certain time?) then THEY pay for a hotel overnight AND if you leave the next day without a car, THEY pay for the airplane back to LA.
But before flying up there, go back to your favorite dealer(s) in your local area and ask them one last time if they will match these offers that you got. That often works wonders, when you show them an email with a firm offer at a firm price, from another dealer. And be realistic: if they will offer you the car you want for $500-$1000 more than you can get up north, just buy it - no expenses, and you skip the travel to pick up your car.
Anyhow, hope it works out for you!
PS: Oh, remember to do a quick check of how much total taxes you will pay this year - not the last little bit you might owe in Apr 2019, but the total of taxes paid when all is said and done. If it isn't at least $7500, you still have a little time to try to generate income in 2018 (say, move money from a traditional IRA to a Roth IRA, or selling stock). Remember that the income you create will be taxable by CA! But at least you will wring the last drop of benefit of the $7500 tax credit from the feds.
