Engine repair service near Countryside, IL

I have high expectations for anyone who works on my vehicles and Rennology was up to the task. They are very professional and completed the work in a timely manner.

Johnny and Ivan are just wonderful guys! Honest and reliable shop! Best labor prices in town. My husband and I don't take our cars to any other shop! I have referred friends and to them and I feel you don't so that unless you are 100% happy with the service provided!

Scratched my car door. Needs paint afterwards

Hands DOWN the best service in town. They are honest, and always do everything to accomidate me. They support my older car nd give me real options on how to proceed when I need to choose the best repair options. I can't say enough good things about the Great service they offer every time I am in. Paul has always helped me and they work hard to get me in and out quickly with a loaner car option (I dont even see that with the dealer any more)! You won't be sorry you called them.

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!

First Choice should be your ONLY choice! I highly recommend these guys to ANYONE! Always professional, very knowledgeable and most importantly they take extra care to make sure the parts being replaced really NEED to be replaced! You never have to worry about them taking advantage of you wife, daughter, sister or friend; you can rely on their honesty and integrity; you will never be overcharged or have any unnecessary work done simply because they think ‘she’ does not know any better. These guys will take you back and show you what needs to be repaired/replaced and even dumb it down if need be. You are always given the option to buy your own parts elsewhere; new or used... or if it’s more convenient then you can trust them to get it for you... Your choice. Lastly, their customer service is A+! It’s all about even the smallest of details like the warm & welcoming family-like atmosphere and caring owners/staff that are willing to go that extra mile... I was once in a pinch and these guys picked me up and dropped me off which helped make a bad situation (a broken vehicle) a bit more bearable. Simplified review: First Choice, Your Choice, The ONLY Choice Auto Repair Shop! Thank you Bill, Melissa & all your staff for everything! PS... they will even tell you when someone else can do something cheaper and make the recommendations if that should be the case. Better than 5 stars! ??????????????????????????????
