3rd vehicle brought from JC…The entire process was quick, customer service was amazing, and without any issues. My husband and I worked with JC and couldn't imagine going anywhere else to purchase our vehicle. Jon is by far the easiest and most knowledgeable person to work with. His passion is the car industry and it shows. We will definitely be working with him in the future again!! Thank you Marino!!

We bought a used Hyundai couple of weeks ago. I think we got a good deal. The dealership was a good experience, specially compared to the other places we had been to. The sales person Christian Gonzales was extremely friendly, helpful and cooperative. His manager Renato Garcia was also a nice person to work with.

Exactly what I was looking for. Lots of trucks
After extensive searching I found a truck at summit auto center that matched my needs. After deciding to buy the truck, the whole process was actually easier than some local deals I have made. The condition of the truck is outstanding! At 6 years old it is in a condition that one would expect of a 1 to 2 year old unit. I am very pleased with the deal. A search for any trucks I may need in the future will start at Summit Auto Center

Highly recommend Kevin Emling at Ford
Awesome experience for my first BIG car purchase! I worked with Kevin Emling to get my dream car in the price range I needed it while the market is still in the hole. We found my car and was never pressured throughout my selection and decisions which at other dealerships in the past I have being a young girl to get something more expensive. The process of getting my car was painless and everything was explained throughly to me on what I was paying as well as my trade in I was over the moon with! If you go to Taylor Ford in Manteno I highly recommend asking for Kevin. If your not able to get him I’m more than sure your in greats hands with anyone else there. Great place will be coming back when I decided I need another upgrade!

Purchase of a certified Buick Regal
I live far from this dealership but they had exactly what I was looking for. The whole experience was very favorable . Everyone I has contact with was very professional and courteous. The salesman I worked with Joe Kendall was excellent. The day after the purchase I noticed that a light strip was missing on one of the outside mirrors. The service dept fixed it. In my opinion they are a top notch GM dealership . Keep up the good work😀
