My daughter was in town for a few days and her car started making a worrisome noise. Dupont’s diagnosed and solved the problem by midafternoon, saving a great deal of stress on a 6 hour drive home.
Thank you, thank you, thank you!

I continue to be so happy with Dupont’s service! I have been with Dupont’s for four years and am never disappointed. I trust their skill, knowledge, and advice. I am a ‘regular’ at Dupont’s because they have the best and most skilled crew in the area!! Their high quality work and attention to detail has never changed. This company is so customer oriented – even in the small routine tasks that occur every six months. Dupont’s had the mundane routine of exchanging my snow tires for my summer tires – all on rims. They were finished the same day – when I came to pick up the car – the snows were all individually bagged(!!) laid carefully in the back of my van, lug nuts were separately boxed!
