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 :)

I continue to think that Duport Service Center is the best auto repair facility that I have ever used, and at 79 years of age I've used a lot of them.

Dupont's did a great job on my van - found the noisy loose bracket and fixed it! Also advised me that I needed 3rd light repair on my van tailgate before my next inspection - asked for my go-ahead to replace light and informed me of cost of replacement. After discussion we decided I could wait another few months before having it replaced. I really appreciate Dupont's honesty and attention to detail about the third tailgate light. Dupont's is incredible because they don't do unnecessary work, they have superior common sense concerning repairs, and I appreciate their honesty. I trust their advice and their work.

We had an unfortunate break down near Dover & we were referred to Dupont's.
Our vehicle problem was diagnosed and corrected by Dupont & the vehicle has been running fine since the repairs were made. We were lucky to be referred to Dupont's. Good service & courtesy.

Don’t change a thing service wise, it is super! If you want something to work on for customer convenience it would be the vehicle parking. I know you are really restricted but even walking distance remote parking may help. Great job !! Al
