He hit all the key points we had previously discussed. Ron introduce me to the Finance Manager, Mark Sonn, so I could get to know all the key people involved in my buying process. About a week later, when I was ready to move forward, everything was perfectly prepared. Mark welcomed me back, and we kicked things off with a BMW welcome video before moving seamlessly into the financial details, expertly handled by Mark Sonn. The entire experience was smooth, professional, and even fun. Ron and Mark truly are the “Blues Brothers” of BMW Catonsville—Jake and Elwood of Sales and Finance in perfect harmony! Jasper J More

I am happy with my purchase from BMW Catonsville. Benn Edwards was my sales associate. He took the time over two days to speak with me, answer my calls, respond to text messages, and the time it took Benn Edwards was my sales associate. He took the time over two days to speak with me, answer my calls, respond to text messages, and the time it took to test driving all 3 cars I was considering. I have had my car for approximately 2 weeks and am extremely happy with my purchase.

Absolutely the best car buying experiences—bar none! I’ve purchased many vehicles over the years, but I felt like family from the moment I walked in because of how genuine and welcoming Korey Mathews w I’ve purchased many vehicles over the years, but I felt like family from the moment I walked in because of how genuine and welcoming Korey Mathews was at BMW of Catonsville. As a result, I purchased three ultra-exclusive BMW’s from him within 3months…the 2025 BMW XM, a 2025 BMW i7 xDrive60, and today I bought the all new 2025 BMW M5! Korey always takes his time to help me select the perfect vehicle, and he’s extremely personable and professional throughout! When it came to financing, Jhonayra went above and beyond to explain all the options clearly and made the process seamless. Honestly, I always forget that I’m in a dealership when I’m with them—it’s that smooth. This is without a doubt my favorite place to buy a vehicle, and I’ve already sent family to Korey…they bought two BMW’s on Saturday! I’ll definitely be giving Korey and Jhonayra my business and all my referrals going forward. I sincerely appreciate how they take care of me and my family! More

Sold my 2017 740 to this dealer about 3 weeks ago. Process took about 20”. However a week later and continuing even today, dealer has sent me several corrected sets of paperwork for signature. Seve Process took about 20”. However a week later and continuing even today, dealer has sent me several corrected sets of paperwork for signature. Several rewritten Powers of Attorney and Odometer statements. It’s as if they’ve never bought a used car before, I’ve been a loyal and happy customer at this dealer for over 20 yrs, both sales and service. The paperwork issue delayed payment of proceeds, though management resolved that issue reasonably quickly, about 9 days post sale. But the requests for corrections in paperwork continues. More

From the moment I walked into the dealership, Korey made me feel welcome and valued. He took the time to understand exactly what I was looking for and helped me find the perfect car. His knowledge of the BMW lineup is exceptional, and he patiently walked me through all the features and options available. Korey was never pushy, always professional, and went above and beyond to ensure I was completely satisfied with my decision. The entire process was smooth, efficient, and enjoyable. If you’re looking to buy a BMW, I highly recommend working with Korey – his outstanding service truly made the difference! Five stars! More
