I've had my Audi serviced several times now at Euro Car Center. Don Bonelli, the proprietor, is a very knowledgeable, reliable, fair and friendly mechanic. He's done everything from oil changes, to new tires, to engine work on my car and I always leave satisfied at the rates and the performance of my car after leaving. I've only had two minor problems (valve stem and rusted splash guard clips) with work performed and both issues were remedied IMMEDIATELY, without any delay, when I brought them to Don's attention. Every job Don performs on my car is shown to me at the time of repair and Don even provides the broken parts he's replaced. I can not recommend Euro Car Care enough for your foreign auto needs in the Merrimack Valley area! Don is the best!6/15/2012 Update: Five stars. Don seems to go above and beyond the call of his duty every time I visit him. A fantastic gentleman, mechanic, and small business owner. We're lucky to have him in our community, and others in the industry should follow his example.
