The Ingersoll employees provide excellent and friendly
The Ingersoll employees provide excellent and friendly service as always whenever I go there for service or to purchase a new car. I highly recommend the dealership.
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Great staff, nice looking cars all over the lot
Great staff, good prices, Greg (salesmen) was amazing, and Jim got me best rate possible even though he didnt have to he kept trying and got me a nice low rate. Now I hope and pray my 2014 Nissan Murano can last me as long as my Toyota highlander did (14 years) before it was totaled while parked. Will look to do business in future with Daddaro Dealer

Great experience
We went to D'addario's about a used Volkswagen SUV. I worked with Ed and he was phenomenal! Never made us feel pressured and the dealership worked with us on getting into the car at the price we wanted. Would highly recommend.

I had a great experience with Meadowland of Carmel.
I had a great experience with Meadowland of Carmel. First off, my sales associate Dominick was a thorough professional who was very attentive to my needs. He understood what I was looking for and found the right fit for our business. In the end we got a great vehicle, were treated respectfully and got a deal we are very happy with. I would highly recommend doing business with MEadowland!

I just purchased up a late model Pacifica.
I just purchased up a late model Pacifica. The transaction was professionally handled. There were no surprises. A hat tip to our salesman Julian and Ken in service, both customer focused. I particularly appreciate their followup communications. It does make a difference where and with whom you choose to do business.
