I brought my car here for a second opinion a few weeks ago regarding the air conditioner not working. Chuck and his team were able to fix it for a small fraction of the price. I am really pleased with their work and highly recommend. Jonathan Dolak

Review Very negligent and irresponsible. Let them know engine had old sludgy oil stuck to engine for last 3 years and did not pass emmisions. I wanted their opinion on the possibility of passing emissions.  After cleaning oil control valve and all passengers in cylinder head. They told me to drive the car and bring back for emmisions check. I drove the car about 15 miles and the engine locked up as a result of work performed. They refused to take responsibility after never letting me know this could happen. They did not advise me that their tinkering could render my car undrivable.  They should have informed of the risk and given the choice of deciding.

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!

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.
