Diagnostic services service near Piscataway, NJ

We've been going to Carlo's for about three years now, and have nothing but GREAT things to say about this establishment. We've dealt with mechanics in several states across the U.S. and overseas, and Carlo's is the most comfortable place we've every dealt with. They are excellent about contacting us with an estimate - and options about repair work (what needs to be done immediately, what we could reasonably do ourselves, etc.) - before making any repairs.

I was very happy yo find out that they work on Europen cars. I have a 2000 Saab that had a blown turbo and Alex was able to find me the best price around and I have had no problem with the turbo ever since. He's very experienced and honest mechanic and I will bring all my cars to him. I will defintely refer him to all my friends and family! If you want good,friendly,reliable,honest service go to Randolph Auto Care!!! -Kanella

Quick and reliable service at a reasonable price! Mechanics are very knowledgeable. Will definately recommend and will use Speed Auto Care next time my car needs service. Sharon B.

This is a one man shop run by a guy named George( the guy who wrote the other review!!). He runs it out of his garage in his house which is located hours from any civilization. I made the mistake of believing the fake reviews and decided to check him out. This guy is a complete hack, absolutely not the expert he claims to be. He speaks of 'process' ever time you ask him a question - basically dumb speak for 'I don't know. If you don't want to have your car damaged for good, avoid this morons at all cost. I ran after I spoke with him for 10 mind after driving 2 hours to meet him.

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. 

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.
