The Acura Advantage team in Naperville are great to work
The Acura Advantage team in Naperville are great to work with and very transparent. The salesman, John Nanni, answered all questions that I had and was able to provide information on the car that I wasn't aware of. Would strongly recommend dealing with Acura Advantage in Naperville, and consider yourself lucky with John Nanni as your car salesman.

Great purchase experience
The Team that my husband and I worked with Dillon, Tim & Dan, were all very helpful and courteous. We had a certain price point and they managed to get us very close to where we needed to be AND we got the car we really wanted. Buying process was seamless, communication was great, and customer service was wonderful. This was our second purchase with Haggerty and we highly recommend!! Thank you

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😀

Hey, yeah - I wanna shoop, baby
When I walked in on Dominic doing a little dance to Shoop (Salt-n-Pepa) I knew this was the place for me. They added no crazy fees to my deal like other stores tried doing during this car shortage. Would come back again.

I would recommend client manager/sales person Bryan
I would recommend client manager/sales person Bryan Druktenis. He is very professional and friendly. He did not pressure me. Lol. Once l purchased my vehicle(s) he was very helpful in showing me how to set up my features and answered any questions l had when l called. Bryan was my sales person for my Acadia that l traded in for the Yukon.
