I was stranded at home with my 2004 BMW parked on the street across town since it stopped running…read moresmoothly. I thought I may have needed to have the engine replaced for thousands of dollars. Matt, the owner, picked me up at home, took me to the car, ran the codes, and figured out the issue was a loose air intake duct. He tightened that and my car was good to go! If I had gone to anyone else, like a BMW dealership, I'm sure they would have taken advantage and overcharged me for a simple fix. I'll be having all my cars worked on at Vaughn's. He's earned a lifetime customer. Best experience I've ever had with a mechanic... Honest and dependable! That's what you want in a mechanic shop and that's exactly what Matt and Vaughn's delivers!

Matt is an absolute angel!!…read more The steep pitch of the Ichiban exit (yes I was driving at a normal speed and yes others have had the same trouble! - but no, the restaurant hasn't fixed it ) caused my car to bottom out and knocked my bumper RIGHT OFF!! We heard a bang and a scrape so immediately pulled over in to the first parking lot, which happened to be Vaughn's Automotive. We called the 24 hour emergency number and Matt came right over to help us! He patched us back together so we could safely drive until we can get a more full repair. He was competent, he was kind, he was helpful, and he was funny ... he took a bad situation and made it as good as we could've hoped for. This is a great and honest and kind man! You can feel confident about placing your trust in him! I drove from Rockford to visit my daughter and thanks to Matt, we still made it to line dancing!!

I am sorry, but apparently you cannot roll any windows down and listen to music while looking at your surroundings because he may think you have an issue. I hope you do not have any kids or grandkids. Your a grown adult yelling at a stranger who is half you age, if that. Don't worry, you know it is him with his license plates being TOPSHELF.
