Here's the response I received from the dealership that I ended up reserving through:
When and if you reserve a vehicle through Subaru.com. You should be assured a vehicle. Brilliance is already adding about $40,000 of just tools and equipment to get ready for having EV vehicles in place. We are going to have parts and service staff trained on 100% emission free vehicles and putting in place charging stations. All expected to take place in the next few months.
Brilliance Subaru is Not charging over msrp, we have no hidden fees, and do not add any packages to any vehicles. Based on current customer information. We have not heard that, about the latter option. That could save you an extra $4K in addendums, that we don't charge. I would reach out to the other dealership and ask for a breakdown of their fees, addendums, and packages required to purchase a vehicle through them. "
Hopefully they follow through. It'll be my first purchase from this dealership after taking it there over the past 4 years for service.
