I have been going to Simons for 20? years. I would not go anywhere else for car repair (except tires). I trust Simons. I know they will tell me the truth. The most important things in car repair are trust and quality of work - and Simons has both.

The work was fine but a little pricey.

by - Verified Customer March 09, 2017

I diagnosed the problem and fixed it myself because they couldn't find the problem themselves.

My family has been going to Simons Serice for years. We are pleased with their service and work that is done on our vehicles.

One reason I have not moved to Missouri is because then I would have to drive all the back to IL to get my oil changed. I love Simons and the work they do.

I took my car in to get an oil changed. The shop recommended that I needed to replace my brakes even though they were recently replaced. I went ahead and got the work done because they are professionals and I trust them. When I picked the car up there was a scraping sound when I turned to the left or the right. They told me it was because I had the wrong size tires on my car even though I have had the same size tires on for two years and have never had this problem. After hearing this sound I took my car back to get looked at again and they were able to improve on the sound, but they were not able to fix it completely. They were honest in what needed to be done, but I felt like they were not trained to work on my type of car.
