Seyit Volkan Tarlaci has built 3A Garage around a clear idea, modern Porsche service is now engineering work as much as mechanical repair.
As Porsche models become more connected, software-driven and electronically complex, maintaining their performance requires a specialist who understands how every system speaks to the next.
From Istanbul Porsche specialist to Costa Mesa workshop
Tarlaci’s career began in Istanbul, where an early fascination with cars led him to study Automotive Engineering at Beykent University.
In 2008, he opened 3A Garage in Istanbul and developed it into a respected independent Porsche service center with a strong focus on diagnostics and mechatronics.
The move to Costa Mesa in 2023 placed the business in one of the most demanding luxury automotive markets in the United States.
While Porsche remains the core specialty, the California workshop also services Bentley, Rolls-Royce, Lamborghini, Ferrari, Aston Martin and McLaren models.
The complexity behind the daily-driver supercar
Porsche’s strength has long been its ability to blend serious performance with daily usability, but that balance also creates technical complexity.
Modern models rely on networks of Electronic Control Units, advanced sensors and high-speed systems such as the PDK dual-clutch transmission.
A fault in one area can be shaped by software behavior, electrical communication or mechanical wear elsewhere in the car.
Diagnostics before parts replacement
Tarlaci’s approach puts diagnosis ahead of substitution, avoiding the common habit of replacing components until a symptom disappears.
His team studies system data, operating behavior and fault patterns to identify the real cause of a problem.
That method has made 3A Garage a destination for difficult Porsche cases, including persistent transmission issues and electrical faults that have eluded other workshops.
Preparing technicians for the electric Porsche era
Tarlaci also places a strong emphasis on training, teaching technicians to understand the reasoning behind each procedure rather than simply following steps.
That mindset matters more as Porsche expands its electric lineup with cars such as the Taycan and the electric Macan.
High-voltage systems, battery management and software analysis are becoming central skills for anyone working on the next generation of performance cars.
For Porsche owners, the value is straightforward, accurate service preserves the feel, reliability and confidence that make the cars worth owning in the first place.
