I've taken my car to DuPont's for my last 2 state inspections. I appreciate their amazing custom service, integrity, and honesty. I am also a fan of how clean their waiting area is.

Well organized, professionally run, "do it all" auto maintenance facility. The staff in the front is very helpful, and the maintenance teams are experts. They have the best tools and equipment, and tons of experience. I have utilized Dupont's several times now for maintenance, repairs, and inspections. Fees and expenses are slightly higher than competitors, but the top notch work done is well worth it!

This business has first rate people interacting with the public. The technical work is excellent as well. I can describe symptoms or work I would like done and leave the rest to them knowing I will get a professional experience. I have always dropped the vehicle off and have not yet needed their courtesy transportation service but it is great knowing its available. I like the fact that I can accumulate reward points that translate directly into money off the bill.

I called at least 10 garages trying to find an appointment when my clutch started making a terrifying noise. Dupont was the only place that genuinely sounded apologetic AND was able to squeeze me in a week before anyone else could. They provided excellent service, great communication and explained all the issues in detail - making sure to explain when a repair was necessary versus preventative maintenance. I highly recommend them for any auto repair you may have. They're obvious passion for their work, teamwork mentality, and friendliness was SO refreshing! Thank you, Dupont's!
