Diagnostic services service near Princeton, NJ

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. 

This is the best mechanic shop I have been to. They are kind, helpful, and reasonable. They always try to fit me in for last minute oil changes and honor my coupons even when I forget to bring them. What you see is what you get, I love that.

Too bad I cannot rate them with 0 stars as 1 is way too much. took my car for an oil change and found an oil piddle under my car the next day. the car is 3 years old and never leaked. took the car to the authorized dealer and they told me that "who ever performed my previous oil change did not do it right". in addition, it did not feel good when they tried to sell me all these unnecessary things including the break system flush after it was done 6 months ago. don't take your car there. they cannot do a simple job as an oil change right, but they will try to sell you everything you don't need.

Sterling and expert service. My '05 Corolla with 315k miles, purrs like a kitten thanks to John and his team at Motorworks. Got an oil change, two new tires and front end alignment. Car is running great. Thanks!

Bitner Automotive is a 3rd generation business started in 1958 as a heavy equipment and auto repair service. In the late 1960, the business was grown to include racing and performance engines. We are constantly investing in new technology to improve our services. Over the past 20 years we've added a dynamometer for engine tuning and a crank shaft balancing system to enhance the machine shop. We have a clean and well staffed shop, and our employees are experts in their fields. Diesel repair, performance enhancement, engine restoration, auto repair, and aftermarket customization are all services that make Bitner Automotive a unique auto facility.

Not recommended at all. Horrible service. OVERPRICED. Go in for a tune-up and am told engine needs replacing???? What's up with that? Tom Matthews was very abrupt with us. Basically told us, we owed him $250 for a tune up without even letting us know price first but engine would only last a month or so. Disagree with Marlene for sure - NOT honest, polite or caring at all.

What an outstanding, ideal, model mechanic and business! After much research and speaking with several mechanics and repair techs, I found Walko Automotive to be the best solution to my bad hybrid battery. Walko Automotive helped replace my 2007 Toyota Prius battery in less than 2 hrs for THE MOST reasonable price. They offered a two year warranty and with their already outstanding business history, Master Tech certifications with hybrid vehicles (and any vehicle really), and a positive, family-oriented atmosphere, they were sure to deliver in every way you would expect the best and most trustworthy mechanic should. Thanks to Andy, Kyle, Diana and the rest of your team involved in helping solve this issue. You all have my business for life! :D :D :D -Julian Jenkins

This is best auto repair shop I found in the area in terms of honesty and price and service! My break were changed quickly and efficiently, I highly recommend this shop and will use them for my needs from now on. And to top it off I got great snacks to take with me!

I have lived in this area for about six years and have tried as many mechanics. After searching for several years I stumbled upon AAMCO and more importantly Jerry the owner of this franchise. I only went here because of a Supersaver Discount I bought for here but I have remained long after it has been gone. Jerry is one of the few honest, down to earth mechanics left in the business. He tells you when things need to be replaced and when they can be stretched out, he really cares about his customers and his workers. His prices are more than fair and when I had my AC fixed and it stopped working I brought it in and he fixed within 24 hours. He stands behind his work and is a man of integrity anyone who comes here will be pleased with the work you get done!
