The difference between Al-Naghi, Al-Majdouie, and Al-Walean

Hello May Allah reward you with goodness Does anyone know the difference between the agents of Hyundai Saudi Arabia which are Al-Naghi, Al-Majdouie, and Al-Walean I would appreciate your help as I am planning to buy a 2025 Sonata Comfort but I don't know the differences between the agents, knowing that the price varies from one agent to another and the difference can reach 10,000 SAR
