Safa Mustafa was an absolute pleasure to work with — professional, patient, and genuinely helpful from start to finish. She made the entire process smooth, transparent, and even enjoyable.

I couldn’t be happier with my new GV70 and highly recommend Genesis of Ontario to anyone looking for a premium buying experience. More

Joesph immediately asked if we wanted any snacks or food for my family and I. The paperwork process was as fast as it could possibly go. Overall from start to finish it took at most 3 hours. More

I just purchased a pre-owned Tesla Y from Simon and Edwin at Genesis of Ontario. I have to say the dealership is absolutely stunning and I was treated like a VIP. Not only did Edwin and Simon make the tran at Genesis of Ontario. I have to say the dealership is absolutely stunning and I was treated like a VIP. Not only did Edwin and Simon make the transaction easy and pleasant, even the GSM came in to just chat with me. It was more than a fair deal and I was in and out in under 90 mins. The finance manger was a pro and had me on my way in no time The experience was even more impressive because I too am a sales manager at another dealership and tend to be a harsh critic. These guys are absolute pros. They even let me know the windshield washer tank was defective at time of purchase and made an appointment to have it replaced. I dropped it off this morning and they delivered my Tesla back to me at my place of work, fully detailed. I can't say enough about how professional and pleasant these folks were from the sales to their service department. I hope we do as well with our customers at my dealership. Two thumbs up! More
