How easy/difficult is it for my dealership to purchase a specific used (2017 Carrera S Cabriolet) from another dealer?

I reached out to the selling dealer which is out of state and so far have gotten a template reply and no return phone call after substantive questions from my end.

Don’t want to misstep but I’d prefer to get another car through my dealership to continue to build the relationship.

If I get from my dealer is there any chance of negotiating price or is it they just buy it from NY dealer and I pay the online price.

How do I make it worth the local dealership’s time, other than they’ll make money on service, and still have some room for not paying list price?

Thanks in advance.
