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
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.

I delivered my Terrain to the service department and waited in the lounge. When the service was completed I paid with my GM credit card. The service department delivered my vehichle after it had been washed.

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.
