As always, Jeff Rizzi and Christopher in the service department took care of us. We arranged to drop-off the car the night before and they've allowed us to do late pick-up after service has closed which department took care of us. We arranged to drop-off the car the night before and they've allowed us to do late pick-up after service has closed which is needed so that we can have the vehicle serviced while we are working. We receive a notification in the morning that they have the vehicle and will call if they have any questions or to let us know that the vehicle is finished. Has been a pleasure to work with them More

Title: Disappointing Experience with Poor Customer Service and Management Rating: 1/5 stars I'm extremely disappointed with my recent experience at this dealership. Normally, I've had positive i Service and Management Rating: 1/5 stars I'm extremely disappointed with my recent experience at this dealership. Normally, I've had positive interactions, but this visit was marred by subpar service and poor management. My vehicle was brought in for a recurring issue with the passenger side window, which wasn't resolved during the initial visit. After dropping off my car on Friday morning, I waited to hear back from my representative, but there was complete radio silence. Despite sending messages and calling the service number multiple times, I was left on hold for over an hour each time, only to be told that the service department was closed and I'd have to wait until Monday. The lack of communication, loaner options, and basic courtesy from management was appalling. The manager, Jeff, seemed more interested in brushing off the issue than taking ownership and providing a solution. His response to the service representative was essentially to tell me to "deal with it" on Monday, without even having the decency to call me personally. This lack of accountability and poor attitude has led me to question whether I'll continue doing business with this dealership. If you value good customer service, I'd strongly advise exploring alternative options. Unfortunately, my experience was severely disappointing, and I wouldn't recommend this dealership to others.
