Mr Thomas Young
I had a great time purchasing my car from Greg Carey. He?s one of the top salesman for Bill Road Mitsubishi very professional. I?ve bought three cars from there and they were all done by him so if you?re looking for a car I recommend Greg Carey.

Van Chevrolet Buick GMC has always been my go-to
Van Chevrolet Buick GMC has always been my go-to dealership for car trade-ins. On 08/15, I leased my fifth car overall?and for the fourth time, I chose Van Chevrolet Buick GMC. The reason is simple: you consistently beat market pricing, but even more importantly, your team demonstrates professionalism, respect, and a genuine commitment to customer needs. Because of this, I always reach out to Van Chevrolet Buick GMC first before considering any other dealer. For this most recent experience, I was assisted by Enzo (Salesperson) and Ahmed (Manager). Both were outstanding in understanding my needs and making the entire process smooth and stress-free. Enzo, in particular, was excellent to work with. He is young, energetic, engaging, and keeps the customer comfortable throughout the process. He made my trade-in experience seamless and positive from start to finish. Unlike some salespeople I?ve encountered elsewhere, who let disagreements or missed deals impact their attitude, Enzo consistently showed positivity, patience, and professionalism. He is a true pleasure to work with. Ahmed was equally impressive?respectful, professional, and attentive. Together, Enzo and Ahmed ensured that the transition was seamless and exceeded my expectations. Thank you both for your outstanding service and for providing exactly what I needed. I truly appreciate your efforts and look forward to continuing my relationship with Van Chevrolet Buick GMC for future trade-ins.

excellent buying experience
Great no pressure place to buy a used card. Anthony was excellent to deal with and very straight forward. I wouldn't hesitate to buy from Munich Motors again in the future. I completely forgot 6 cd's in the car I traded in, and Anthony texted my to let me know they found them in the stereo. Thanks a bunch for an easy purchase!
