About Auto Care Plus: Your Trusted Auto Repair Experts with 17 Convenient Locations
Since 1984, Auto Care Plus has been proud to serve the automotive needs of our communities with a commitment to quality, integrity, and exceptional customer service. Family-run from the very beginning, we’ve grown thoughtfully over the years to now proudly operate 17 locations across New Hampshire, Maine, and Massachusetts.
Our journey began at 738 Daniel Webster Highway in Merrimack, NH, where our original location still thrives today. Fueled by our passion for excellence, we expanded in 2011 with a second location in Manchester, NH, and ventured into Maine in 2013 with a third location in South Portland.
In 2014, we embraced the scenic charm of upstate New Hampshire by acquiring our Wolfeboro location, followed by Conway, NH in 2016 — two destinations that not only offer outstanding automotive service but also beautiful drives through New England’s best vacation spots.
In 2017, we grew again by acquiring our Hooksett, NH location, initially specializing in European vehicles under the name Euro Care Plus. To avoid confusion and better reflect our expertise across all makes and models, we soon rebranded it as Auto Care Plus.
In 2019, we celebrated the grand opening of our largest facility to date: a 12-bay, state-of-the-art service center built from the ground up in Derry, NH.
Our expansion continued into 2022, when John and Karen Manelas acquired Roberts Auto Service in Lebanon, NH, welcoming it into the Auto Care Plus family while proudly maintaining its trusted local name and reputation.
Since then, our growth has accelerated with the addition of several outstanding locations:
- 10th: Dupont’s Service Center in Dover, NH
- 11th: Ronnie’s Total Car Care in Billerica, MA
- 12th: Bayside Auto Center in Fall River, MA
- 13th: Mike’s Car Care Center in North Grafton, MA
- 14th: The Specialists in Merrimack, NH
- 15th: Windham Mobil, now proudly operating as Auto Care Plus in Windham, NH
- 16th: Kezar Automotive in Chichester, NH
- 17th: Quick Stop Tire Shop in Plaistow, NH
Wherever you visit us, you can expect the same high standards that have defined us for decades. Every Auto Care Plus location is staffed with ASE-certified Master Technicians, backed by advanced diagnostic tools, and committed to providing clear, honest service.
To keep you informed, we deliver digital vehicle inspections right to your phone — complete with over 15 detailed photos — allowing you to see exactly what your vehicle needs.
As a NAPA AutoCare Center, we proudly combine the benefits of a nationally recognized brand with the personal touch of a family-owned business. We know your vehicle is a major investment — and we treat it with the same care and respect we would our own.
Stay connected with us on Facebook, Instagram, and TikTok, where we share behind-the-scenes looks at our work, car care tips, fun projects, and a few laughs along the way.
