The Dealership

Mercedes-Benz of Smithtown was established in 1995, but our roots reach back to 1962, when Joseph C. Buzzetta founded the Competition Auto Group. The Buzzetta family still runs Mercedes-Benz of Smithtown today, alongside its sister stores — Mercedes-Benz of Huntington, Competition BMW of Smithtown, and Competition Subaru of Smithtown — all built on the same foundation of family.
