Jorge gave us a great experience with buying our car.

Jorge gave us a great experience with buying our car. He was helpful and knowledgeable in getting us into the car we wanted within our budget. We are senior citizens with limited tech knowledge but he guided us through the process and helped us understand the options on our vehicle.

Proactive Service

It started when Matt saw me drive in to the service bay and walked over to greet me with a smile. I had a question about our navigation screen that honestly was driving me nuts—he showed me how to fix it in a jiffy. We were in for a simple oil change, but Matt also after checking our tires warned us that new tires would be coming due and provided a few estimates so we could prepare for that upcoming expense. We always feel special at Skillman because of members like Matt.
