I almost never leave reviews, but Brian and the team at Islip AutoWerks absolutely earned this one…read more I brought my car in expecting a routine service and left wondering why I ever went anywhere else. Brian replaced my entire braking system, performed an oil change, thoroughly inspected the vehicle, checked all of my fluids and critical components, and even provided photo documentation so I could see exactly what was done. That level of transparency is incredibly rare. What impressed me even more was his honesty. I was fully expecting a much higher bill based on the quality of the work, but he actually undercharged me. I ended up tipping him because I genuinely felt like I owed him more than what he charged. Brian is humble, down-to-earth, and clearly takes pride in doing things the right way. Pulling into the lot and seeing McLarens and Maseratis being serviced tells you high-end owners trust him, but he treated me and my car with the exact same care and respect. Finding a mechanic you can trust is difficult. Finding one who's honest, meticulous, communicates everything with photos, and charges fairly is almost impossible. Islip AutoWerks has earned a customer for life, and I'll be recommending Brian to everyone I know. Jason Finnerty
