Emissions testing service near Piscataway, NJ

STAY AWAY. FIND SOMEWHERE ELSE unless you want poor quality. I paid for an oil change and they didn't put the oil cap back on afterwards. My car made rattling sounds and smelled of fumes and knowing they were the last to touch my car I lifted the hood and the oil fill cap was bouncing around rather than screwed back into place. Oil was everywhere under my hood. I went back to inform them, they checked the oil level, didn't offer to clean up any of the oil, and made no apologies. I gave them another chance and asked for a quote to replace front tires and brake pads. They wrote my info down and three weeks later I still haven't heard from them. They seem like nice people, just incompetent and clueless about simple sensible customer service. They get an F from me. I don't recommend them for any type of car service.

If you live in central/south jersey (or a reasonable distance).  Owns a car you care about and/or plan to own for years. Don't want to pay dealership price for the same, and in most cases better customer and car service.  And/or need a knowledgeable, trustworthy, dependable, courteous and cost-effective auto technician...YOU SHOULD KNOW UNION LINE GARAGE IN HOPEWELL.   These guys are one of the best in the business. I have so much confidence in them that 'twas it not for legal reasons, and the size of my bank account...I would offer to pay for your repairs at another shop if you can prove said shop provided better workmanship, price and service than Union Line Garage.
