A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

As someone who had just immigrated from Korea, I had to
As someone who had just immigrated from Korea, I had to purchase a used car due to budget constraints. While I would have loved to buy a BMW, I ended up purchasing a Hyundai Santa Fe that BMW had taken in as a trade-in. The dealer I worked with, Gennaro, was exceptionally kind and responsible—so much so that he genuinely influenced my perception of BMW as a brand. One of the main reasons I chose this vehicle over cars from general used-car dealers was the trust I had in BMW’s basic inspection and standards. However, the way Gennaro handled everything afterward gave me even greater confidence that I had made the right decision. Having just arrived in the U.S., everything felt unfamiliar and overwhelming at times, but this experience reminded me that there are truly good people here. Honestly, when the time comes for me to change cars in the future, I sincerely hope to return to BMW and purchase a new car from Gennaro. I would even say that owning a BMW through him has become one of my mid- to long-term goals for my life as an immigrant over the next five years.

I purchased a 2025 Mazda cx70 with the help of Kenneth at Boucher. He wasn’t pushy and actually made the whole car buying process a little less terrible! The manager was also willing to work with me on numbers to suit my budget. If you’re in need of a Mazda, ask for Kenneth!
