As always, Jeff Rizzi and Christopher in the service

Reviewed by JOE@SJDINC.COMDecember 08, 2025

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 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
