Good stang shops in NJ?

LaRocca's isn't owned by Jimmy LaRocca anymore and there have been a few
horror stories posted recently - a search is your friend.

JDM does great work, they are not cheap and they are hard to get an appointment.
When I'm ready for a chip for my Saleen, they are the only ones I will let touch the car.
 
Difeo Ford in Jersey City....you will not be disappointed. It's an authorized Ford Service Center. The service manager is Travis and he has a modded 03 Cobra. His Ford service place does anything you want done on a Mustang. He will also go out of his way to get something done through a warranty for you if you have the warranty still existing.
