It looks like it might be closer to Hwy 99 at 3131 Auto Center Circle, but at least from the permitting portal this is indefinite since these are just fee estimates. But this is great news! It apparently includes a service center as well as sales. See the following:
EST20-01883 - 04/02/2020 - Fee Estimate for: TI for Tesla auto sales and office
EST20-01940 - 04/06/2020 - Fee Estimate for: Tenant improvement of existing auto dealership into a Tesla repair shop and auto sales.
