As always, the folks at DuPont are efficient and courteous. I feel our cars are well cared for. They suggest additional maintenance only if needed and I never feel there is a hard sell or upselling such as at a dealer.

My vehicle needed brakes and a couple other things. Many recommended Dupont's to me and I could not be happier! Communication was on point from my initial inquiry through picking up the car. I was sent a full report, including pictures, an estimate, and was kept informed throughout the day of the status of work being done. They've earned a repeat customer!

Courteous, friendly, efficient, continuous monitoring to keep us safe on the road. Trustworthy.

Brought a truck here on a test drive from the dealership nearby to have a mechanic dig into it for me. In and out in 30 minutes, they did a full inspection and even test drove it themselves. Highly recommend Dupont.

I had an appointment to get my car inspected, I had never been here before. The service was quick and kind! The seating area was large, clean and supplied with a beverage station (coffee, etc). Definitely taking my car here for future services!

I took my 2022 Subaru Impreza hatchback here for state inspection. Had such a great first experience I returned for a new tire after getting a flat. Josh went above and beyond to help me and really made a stressful situation, stress free! Ryan is such a sweetheart and I always enjoy our rides. Absolutely love this place and will not hesitate to return for future service.

This is my go to service center for auto issues. They are trustworthy, thorough and competent. Here’s 2 examples of why i trust and appreciate DuPonts: Several years ago a Dover Toyota Dealer contacted me regarding a recall for my 2013 Tacoma. They did the recall and told me that the emergency brake cable had to be replaced at a cost of $880. I declined because i was aware of this dealer’s reputation. Service advisor said truck would not pass state inspection (4 months away). A couple months later i had DuPonts replace front brakes. When I picked up Tacoma the invoice showed that they also “adjusted emergency brake, no charge”. The other example is a Portsmouth Mercedes dealer. Took advantage of a discounted “Schedule B Service”. As is typical of this dealer, they recommend additional work based upon issues that the technician uncovered. When I dropped off car i told my wife that they would likely call me and recommend about $2,000 in additional work. Well, I was wrong, when I got the call a couple hours later the service advisor advised that the technician surfaced several issues that needed to be addressed. (Alignment, rear brakes, idler pulley). I asked the cost for the repairs and he said about $7,500. I told him not to do work. Took the car to DuPonts, asked them to rotate tires, do an alignment and check rear brakes. Got the car back later that afternoon. Alignment was adjusted & tires rotated- cost was $144.45. DuPonts also did a complimentary and thorough 44 point inspection of my 2014 E350 (61,000 miles.) The car passed every category with rear and front brakes having minimal wear and in good condition. DuPonts $144.45 vs. MB $7,500 Need i say more as to why DuPonts is my go to service center?

I love DuPont’s service. Great people that work there and they are so friendly. A little pricey but the price matches their customer service and work that they do. I go to college at UNH and whenever I need work done on my truck they are the first person that comes to mind. 100% recommend this service center for any work that you need done on your vehicle. They offer their own taxi service at no cost too, so no having to wait hours or Uber back and forth if you do not have a ride.

Did a good job at resetting new windshield in timely manner.
