dealership - Longman Contemporary English =>
      A business that sells a particular company´s product, especially cars: Nissan dealerships.

      Para mim =>

    franchise, vendas, negócios, revenda, concessionária (autorizada pela devida marca-mais apropriado pra vendas/revendas de carros), comércio.

      Enfim, todas as palavras acima, contudo usadas mas no negócio de carros (e no sentido de lojas e vendedores "fidelizados"  (e/ou detentores de autorização para revender uma determinada marca de carro, ou mais de uma).

Aqui (na letra da música), poderia ser loja de carros (concessionária/agência):
Nigga you's a window shopper
In the jewelery store, looking at shit you can't buy
Nigga you's a window shopper
In the dealership, trying to get a test-drive
Nigga you's a window shopper
Mad as fuck when you see me ride by
