Emissions testing service near Naperville, IL

Truly thankful for this establishment today. I was in a bad spot very close to the end of their business hours and they still helped me although they could've sent me on my way. A special thank you to Rachel & Tommy. You guys are the best! Dion Y

Great people who tell it like it is. Honest, clear, professional and personal care you know you can trust 30 seconds after walking in. My first visit cost more than I had hoped, but I left fully satisfied and confident in the work done. I came in on a referral by a long time customer and expect that I'll also be recommending Doc Motor Works for years to come!

I was pretty excited about Wrench. They came to me and did a diagnosis on my vehicle. Said they would need to order parts and reschedule an appointment. I was excited that the $75 diagnosis feee would go toward my repairs. They returned for the second appointment and the parts ordered weren't the correct parts. I never heard from them again... I had to pay another mechanic another diagnosis fee. I was pretty bummed. ? I think this service would be great for simple things, Oil change, etc. but if parts need to be ordered, I'd suggest a brick and mortar. Ryan S.

Have been dealing with Dakota K for many years, they have always provided knowledgeable service at competitive prices and great customer service

I have had Jim at Advanced take are of several of my cars over the last year.I found this shop to be very fair and they got the work done quickly. I would recommend this repair shop to everyone.

Once again, you guys rock! Thank you so very much!!!!

I was so lucky to have brought my car for service on Monday. I have had so many bad mechanics try to fix my car but Velasquez and Darwin FINALLY got to the root of the problem and fixed my check engine light that was on for months. Other mechanics claimed they fixed the check engine light problem but the didn't. It is NOT easy finding a good, honest mechanic these days. I know I finally found one and can confidentially bring my cars to Velasquez in the future. Darwin also changed the gaskets. I had paid a mechanic to change them a few months ago but apparently didn't. I actually paid to have the purge valve and gaskets changed but they never were. Darwin even showed me the defective parts. Thank you Darwin and Velasquez mechanic shop. Brian 2-9-22
