I've been using Dwayne's DuPage Auto Werks service for approximately 10-15 years. A couple days ago, he changed my oil, installed a new battery and performed a general check-up on my car. I have another appointment for my car in a few days. I continue to take my car to Dwayne because I think he is very honest and reliable. I feel like every time I visit him I can trust that what he's telling me about my car is true.
