Sean and Jamie were incredibly helpful.
Sean and Jamie were incredibly helpful. Initially I was looking for a car they were not selling but they helped me anyway, ending up in a sale for them, and a great deal for me with a car in my budget. They were really great to work with, transparent, showed me all my options and gave me time to make my decisions. Sean in finance was great to work with explaining things very thoroughly. Really appreciate the professionalism from these gentleman.

Dennis Dillion GMC Service Department.
I always take my truck (2016 Chevy 2500HD LML) to Dennis Dillion for service and repairs. I recently had my Alternator replaced under my extended warranty and Brandi Jacoby my service representative processed the claim and received approval enabling them to complete the repair quickly. I am back on the road and my truck is performing like new I would always recommend Dennis Dillion for anyone who appreciates a professional and kind service department.
