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.

First time at this dealership to purchase a vehicle everybody I came into contact with were very friendly, knowledgeable, and professional. Juanita and Khaled Nasser were excellent.

I thought I should have gotten a better price on the car but who doesn’t? Kahled was my salesman and I couldn’t have had a better person. He is a very caring person and does his best to make everything in the deal go right, for the business and the customer.
