We go to Dupont's because we trust them. Never feel like we are being unsold or doing unnecessary work. I used to go to my dealer for service. Not so much anymore. Our first choice is Dupont's
Thank you :)

This company is amazing!! Completely rebuilt the exhaust system on our very ancient (2008 Volvo Sedan). Plus gave us honest advice as to whether we should proceed with the expensive service or not. Truly had our best interests at heart. Our Volvo is running better than it ever - and we have had this car for a very long time!!! Price charged was less than estimated and as explained was so much cheaper than trying to replace the old car with a used car of similar quality and reliable operation. (We did do some market checking - DuPont 's was exactly right!) The people who work here are honest, hardworking, and experts in their field. Plus they have a plan that you can join where you receive bonus dollars applicable to future service. I used the $50 from this program to help pay for the bill for this Volvo.

It was our first visit to DuPont. Engine light on eleven yr old car. We are very, very impressed with the texts communicating progress through the repair process. At each step we were advised of the progress , possibilities and choices to be made for our car. DuPont is our service provider from now on.

I cannot say enough great things about DuPonts. It’s clean. Staff are so friendly and helpful. Their shuttle service is wonderful and saves stress and time. They update frequently with texts and email. They are professional at all times. They are knowledgeable and can explain things in a way I can understand. I will not go anywhere else.
