I wanted to share my incredibly positive experience with Sal, who is not only one of the best mechanics I've ever encountered but also a truly fair and honest individual.

My car required an overnight stay for the necessary work, and Sal kept me informed every step of the way. He sent detailed photographs of the damaged parts, clearly numbered and explained their functions, and even provided options for replacement, including tips on how to save money on parts.

Before I found Sal, I had unfortunately been taken advantage of at two other places. I paid for parts that were never replaced, and my car continued to have issues. I was so concerned about my daughter's safety and the potential risk my car posed to other drivers that I was considering getting rid of it entirely.

Sal's guidance throughout the process was invaluable. In just one weekend with him, I learned more about mechanics than I had in my entire life. I wholeheartedly recommend him for his professionalism, honesty, and fairness. Many thanks Sal!

Sal is the goat !!!!!
I wanted to install an after market intake system for my car (Since it's an after market part so the fitments were kinda off which made the whole process a bit diffcult). But Sal's very professional and very patient during the process. He also made sure everything's fine no leaking & no check engine light.

Had a plethora of electrical issues.. Sal not only resolved said issues, but also walked me through every step of the way, while also keeping me up to speed about the current steps being taken, along with the steps needed to be taken in the future.. 11/10 experience; definitely recommend, definitely will be using their services again.

Sal is awesome! He helped me with a pre-purchase inspection and saved me thousands of dollars. The dealer was trying to hide issues with the vehicle's transmission, but Sal was able to find those hidden codes and advise me on my purchase. He is very patient and detail-oriented. He is also very friendly and truly cares about his customers. He took time out of his day to explain everything to me in detail. I would highly recommend his services!

I called Sal to check on a noise issue I was having coming from my wheels, he diagnosed and solved it within 15 minutes, very efficient. I'd recommend using him auto needs. Also he doesn't charge if he can't fix the issue.

Great service, I needed a headlight replaced urgently and was able to meet with him just 10 minutes after calling. Walked me through his entire process and was more than fair with pricing considering it was a rush job. Thanks again!
