HM Motor Works is the independent automotive service and repair shop of Haleem Mediouni. Haleem has always been a car fanatic, with interest in premium European automobiles. Haleem and his team of dedicated technicians and service writers ensure that their customers stay where they belong; back on the road! HM Motor Works was founded in 2011, although Haleem and the staff have many more years of combined experience working on cars. Using that experience to bring more value to their customers is what HM Motor Works is all about, they often fix problems more quickly and cheaply than other Merrimack area auto service facilities.

The HM Motorworks Team features one of the deepest pools of professional mechanic talent in the Northeast with well over 100 years of combined european and luxury automotive repair experience!  Experience plays a huge part in a mechanic’s ability to accurately identify and effectively correct problems, but the automotive industry is changing at a phenomenal rate. To ensure that the HM Motorworks team is always at the cutting edge of new vehicle technology we invest significant time and energy training on new vehicles, and maintenance techniques.  We utilize the same approach with our vendors, partnering with the same suppliers that the dealerships use. Lastly we operate our repair facility using a team collaborative approach, so we are equipped to handle whatever comes through our doors. We invite you to give us a shot, and we appreciate the chance to earn your business!

HM Motorworks is Southern New Hampshire’s premier luxury automotive repair facility specializing in Acura, Audi, BMW, Cadillac, Infiniti, Land Rover, Lexus, Mercedes Benz, MINI, Porsche, Tesla, Volkswagen, and Volvo.  We are conveniently located at 26 Columbia Circle in Merrimack NH, easily accessed from points North or South via the Everett Turnpike, and D.W. Highway.
