Established in 1964, J&M Auto Repair has been a cornerstone of dependable automotive service in Nassau County for six decades. Located at 90 Underhill Boulevard in Syosset, NY, directly accessible to commuters near the Long Island Rail Road (LIRR) Syosset station, the facility combines classic neighborhood service with modern diagnostic capabilities. Under the leadership of Michael Dolinsky and Randy Williams, the shop is a recognized NAPA AutoCare Center staffed by skilled, ASE-certified automotive technicians equipped to handle all foreign and domestic makes and models.
From routine factory scheduled maintenance and New York State safety and emissions inspections to complex engine diagnostics, transmission service, timing belts, and brake repairs, J&M Auto Repair delivers bumper-to-bumper care. They also support local commercial fleets, assist with end-of-lease vehicle cosmetic and mechanical restoration, and work seamlessly with major aftermarket warranty providers and insurance carriers. Commuters and local drivers further benefit from 24/7 towing and roadside assistance, flexible pickup and drop-off coordination, and convenient after-hours key drop options.
At the core of J&M Auto Repair's business model is transparent, upfront communication. Rather than surprising drivers with unexpected line items, their technicians prioritize educating vehicle owners and walking through itemized estimates before turning a wrench. This honest, customer-first approach has fostered multigenerational loyalty throughout Syosset, Woodbury, Oyster Bay, and surrounding Long Island North Shore communities.
