Elite craftsmanship, honest leadership, and true car people…read more This shop is the definition of how an automotive business should be run. Sami, the owner, brings a level of experience and integrity that's rare today. You can tell immediately he's not interested in shortcuts -- only in doing the job correctly, responsibly, and with long-term ownership in mind. That mindset flows through the entire operation. Amal is equally impressive. She's professional, knowledgeable, and incredibly organized, making communication smooth and transparent from start to finish. Together, they've built a shop that runs efficiently while still treating every car with genuine care and respect. They previously handled a major drivetrain project for me (BMW E38 M62TU swap), and the execution was flawless -- clean work, fair pricing, and no surprises. That level of trust is hard to earn. Because of that experience, I'm now confidently bringing them another special vehicle for a full recommissioning. I wouldn't do that if there were even the slightest doubt. If you're an enthusiast, collector, or simply someone who values honest work done right the first time, this is the shop you want. Sami and Amal run an operation that sets the standard. ( Sami also has a pristine Carrera 993 air cooled ) Highly recommended.
