About Us

DT Performance Garage is a veteran and family-owned mobile mechanic service serving Passaic County, NJ and surrounding areas. Built on honesty, quality workmanship, and fair pricing, we bring reliable automotive repair directly to you.

Before DT Performance Garage, we started Off The Line Detailing LLC in 2024 with the goal of providing professional, trustworthy service to our community. As we continued working with customers, we saw how hard it can be to find an honest mechanic who takes pride in the work and treats people fairly. That is what led us to expand into mobile mechanic services.

Michael brings hands-on mechanical experience developed during his time in the Marine Corps, where he worked with heavy equipment, marine systems, and diesel engines. That background gave him a strong foundation in diagnosing mechanical issues, problem-solving under pressure, and performing work with discipline and attention to detail.

Dominic brings extensive hands-on automotive experience with a strong focus on repair, maintenance, performance, and custom vehicle builds. Over the years, he has helped build and service a variety of vehicles, developing a deep understanding of how to approach each job with precision and care. His passion for performance is reflected in his own custom-built Miata, as well as his current project of building a higher-performance engine for the car. Dominic’s attention to detail, mechanical knowledge, and pride in quality workmanship help ensure every vehicle is treated with the level of care it deserves.

At DT Performance Garage, we are committed to treating every customer with honesty, respect, and clear communication. We take the time to explain what is going on with your vehicle, help you understand your repair options, and provide honest recommendations without pressure or unnecessary upselling. Our goal is simple: to deliver exceptional service, quality repairs, and fair pricing you can trust.
