NON LBC Garage help in Northern NJ

[<boggiano@charter.net>]

My Parents seem to have a problem with their Chevy Malibu associated with 
coolant levels, Evidently they had none. They had it refilled and the garage 
said that the needed a new head gasket. 

They have no leak or evidence of one under the car and since refilling, it has 
held the coolant level. 

Does anyone know of a reputable garage in the area of Ft Lee/ Leonia/ Palisades 
Park that I can direct them to?

Thanks
Tom
