I've had the 2025 X3 30 now for 5 months and it is great! It replaces our 2022 X3 that was recently totaled and both passenger walked away with just bruises so it is a safe car! This is one reason I purchased another X3. Big difference on the interior panel than the 2022 as everything has gone to touch screen for all controls which I not real fond about, even the owners manual is on the touchscreen software, The twin turbo gives plenty of power and the gas milage has improved from the older model. The gears change smoothly and the ride is also smooth. You now get a spare tire since BMW did away with the run flat tires which I hated as they did not wear great. The accessories offered in their package covers everything you want in an auto. I don't understand why the rear exhaust are hidden though as I like the chrome exhaust on my old 2022. This year the 3 was redesigned and it is slightly bigger.

Tyler was so great to work with. Zero pressure to buy, or to add anything I didn’t want.

First class operation from beginning to end. Good communication throughout. Condition of vehicle more better than described.

Julius very perfessional. He answered all my concerns and my car and all work was completed in a very timely manner.

Was this a perfect transaction? No. Would I recommend them? Yes. Some things went wrong, most things went right. They answered questions, they answered calls (and I called them a lot) I bought a car online from photographs. They delivered the car I bought plus sent a small refund, an unrequested refund. What car lot does that? They pointed out the negatives to the car, took more pictures when I asked, double-checked some things for me. I found them to be professional.

Adam Gladden knows his product and dealership. professional, caring of the customer. I always ask for Adam

Adams in the service department is top notch. My appointment was for an oil change.

I have bought several cars from this dealership and have had Abraham as my salesman on a couple of occasions. Wonderful service and such a friendly salesman. I would definitely recommend this dealership and this salesman.

I was hesitant about working with a dealership out of town but I was extremely happy with how Ryley, Julianne, and Travis took care of me. They were thorough and handled my transaction detail’s without any issues. Everyone was welcoming and professional. I would not hesitate to purchase from them in the future. Thank you!

ONYX Automotive made my out-of-state vehicle purchase really smooth and simple. I was initially nervous and skeptical, but Max was amazing. He walked me thru the entire process and was always communicating with me. There was never any hidden fees either. Great experience!!!

Service department was nice and efficient. The parts department was fast in helping me get all weather mats with my vehicle as well. The dealership was clean which made it a pleasant experience too.

I love Galleria! Always Great Service and knowledgeable sales people. Everyone there is so helpful and the atmosphere is great! Thanks Galleria, I will be a life long customer.
