Emissions testing service near Princeton, NJ

My check engine light went on and that drives me nuts. Suburban did a complete test and thought it was my old gas cap. After several gas fill ups the light went out today out of the blue. Thanks to Mike and my new Honda gas cap.

Professional and honest are the 2 words to describe J. Scuderia. I am 100% satisfied with the work on my vehicle and will continue to use them for all of my Ferrari services. John P

What can I say other than Hendersons has the best customer service I have ever experienced in the automotive repair industry. We have been going there for approximately 10 years now, multiple cars under Ed's care (having 3 children of driving age) and do not have one complaint. With my busy schedule, they always find time to fit us in and do the best job ever!!!! We are big fans and would recommend Hendersons to all. Stephaine A. Millstone, NJ

Honestly, they are the last of their kind. They are honest and truthful and put their customers miles ahead of any desire to make money.If you have a problem with your vehicle and they diagnose it and find out fixing that problem may not help your vehicle work properly they will tell you instead of just taking the money. This is a really great group of people! They go miles out of their way to help their customers.

Always outstanding service when I take all my cars there.

Had an emergency over a weekend. Called on a Monday morning. Don got me in, fixed the issues, and I'm safe on the road again. Couldn't have gone better! Thank you!

This place has changed a lot. It is not the same as when I first started coming. Under new management, and I noticed new employees also. The service just isn’t as great as before; it has gone down. There’s no more friendliness or professionalism. When you ask a question, it feels like they either don’t know the answer or just refuse to answer and give you a blank stare. It’s so sad when companies go from good to bad because people just don’t care about their customers or clients anymore. But I will not be bringing my business there anymore. It is so sad to see this place go downhill. I wish you guys luck in the near future.

KPS did a great job replacing the clutch on my BMW. The price was fair, much lower than three other places we called. Plus the warranty is great. The turn around time was fast. They washed and vacuumed my car when they were done. A pleasant surprise. I will return to KPS for all our families car needs. Very professional and informative.

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.
