Engine repair service near Mchenry, IL

This place is my heaven on earth. If i could give more stars i would. Weve had them work on our 2009 yukon denali, our 2012 chrystler 300, and our 1999 mitsubishi eclipse. The last job i brought them was a 1987 Chevrolet C20 pickup. The transmission needed a rebuild. They did it in under a week, and they even beefed it up for just 100 more bucks! It was smooth, down shifts were incredible, the whole shabang. Everytime i hear someones having a problem with a car we dont know how to fix, this facility is my first recomendation. These people are so great, ive called asking their opinions on a noise and instead of giving me the same old same old ever shop does, "well.... youll have to bring it in and well charge to look at it" theyve helped me over the phone asking to describe it. Ive even had the receptionist pull a guy from the garage for his opinion! The only bad thing i have to say is, ive called numerous times to set up an appointment and tbe problem gets fixed by itself or i fix it, then forget to call and say its a no go on the appointment, or i do call and i emd up canceling. I feel so bad every time i do it because they are really good people! Thats my fault not theirs though. I have a 1973 corvette that was recently involved in a rear end hit, as soon as the body shop finishes with the back, everything i need done to it will be going to Natiomal Pride. I recommend this place to anyone with any car problems they dont feel confortable with doing! Dylan S. Gurnee, IL

Machined & assembled short block, when I went to finish assembling it, noticed a few things I didn't like. Ended up Paying a different engine builder to redo everything Dons did. Other service was just not the quality I paid for. I would not recommend them to anyone.

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!
