I’ve been working with Souhardah since 2021, and he always makes the experience smooth and enjoyable. He’s friendly, patient, and consistently provides excellent service. I love my new Mercedes! 🖤

I went in knowing I wanted an EV. The vehicle I drove away with exceeded my expectations. I?ve been looking for other EVs on the market and EQS SUV 580 makes other EV looks like toy cars. This vehicle is so luxury and smart. Mercedes thought of everything. And the air freshener is amazing.
