As someone who has been part of the goth and alt scene for decades, I don’t just drive a car, I curate it. I roll around NYC in a blacked out Cadillac CTS V that fits my age, my taste, and my love for things that are loud, dark, and unapologetic. When it came time for tuning and upgrades, I took it to True Street Performance and honestly, I could not be happier. From the moment I dropped the car off, I felt like I was dealing with people who actually respect craftsmanship and individuality. They listened to what I wanted, didn’t talk down to me, and clearly knew their shit. The tuning was spot on, the upgrades were done clean, and the car came back feeling tighter, meaner, and more alive than ever. What really stood out was the care. This wasn’t rushed or cookie cutter work. They treated

I recently had my charger serviced at true street and I am extremely happy with how quick and efficient this shop is. They diagnosed the problem right away and had my car running again in no time. The prices are also very fair. Whenever I leave my car here I know it’s in good hands. Thanks again!

I’ve known Jim for over 20 years He built my 2006 charger SRT8 It’s in the shop right now getting another supercharger put on it. It has a 426 stroker. He just helped me with my C8 Corvette. I had a problem with the catalytic converters. I could honestly say he’s one of the best mechanics out there. He’s honest if anyone’s looking to get the car worked on I would definitely recommend him.

I did a lot of research on company’s up and down the east coast on hellcat hemi tuning and performace , And I’ll say true street performance, Jim the owner was the who stood out amongst all of them, actually took the time to talk , and NOT treat you like another guy spending money on a car!! That speaks volumes for me! We went over what I was looking for how that could be achieved and even with a budget he still managed to get everything in , I truly recommend this shop if you’re looking for anything. His crew of guys and work is amazing! Looking forward to tearing up the street thanks everyone at true street performance!
