Stranded 2,400 miles from home can be frustrating. Finding a reliable diesel repair shop in California was a crap shoot. Stopping in Gilroy, the garlic capital of the world, answered our prayers Sarah was very responsive to all our concerns and questions. We dropped off the vehicle on Wednesday and had an estimate in hours. Torn O-rings on 2 injectors needed replaced. Tearing off the top end and and returning to us by Friday was a tall order. David assured us they could deliver. Friday at 3pm we were on the road again. Kudos and accolades to Sarah, David and Wayne!! I would drive across state to hire Preferred again! Thank you Mark
