Mufflers repair service near West Chicago, IL

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

Wrench was right on time and Scott Giller did a brake inspection and even diagnosed my airbag problem for me. I trust Scott with my car. Gale Rogers

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

These guys are by far the most honest and reliable repair shop I've seen on a long time. Being retired from the car business, I know a good one when I see one. Don't waste your time shopping around. Go straight to them. You won't be disappointed I assure you. Jim Monti

Very professional & knowledgeable. They informed me what my vehicle.

This is a very convenient location for me,and my family has used Frank's for years. The service is great and the prices are always on point. I really like being able to drop off my car, then walk across the street and catch the metra into work.

I took my ML 350 due to a problem with the Engine. The drive chain had broken. The dealer's recommendation was to repair and cost was something of buying another car! So, I took to Dupage Auto Werks. The recommendation is to replace the 118K miles engine with a much lower engine. They shopped and found a fimilar engine and practically did a 'Engine Transplantation'! Now that I have an engine not only has a lower mileage, but also was cheaper overall. Very satisfied with them to have suggested and able to get my car worth somehting that I can keep it a much longer time!

Recently had my '06 F150 repaired by Tony. I highly recommend Tony for repairs to 5.4 Triton engines. My engine developed the now famous Ford Triton "tick". Tony gave me all my options and fixed the problem. The charges were very reasonable. Great job, thanks Tony
