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.

JC and Marino dealership provided an exceptional
JC and Marino dealership provided an exceptional experience. JC walked us thru all the benefits, applications and dashboard to be sure we knew all the wonderful features of our new Jeep Grand Cherokee. In addition to knowledge sales people, the process of buying a new car was seamless. Everything from getting the registration card, license plates and applying for the title happened in JCs office! Everyone was super friendly and excited about our new car. It felt like we were treated like family… that’s how much care and attention we were given. 10 score all around!!! Thank you JC and Marino team.
