Performance Shops in Atlanta Specializing in Mercedes-Benz and Porsche Auto Service and Repair


With 84 years combined experience, RS Motorwerks is the premier independent Mercedes Benz and Porsche® German auto repair center in Atlanta! We are a family-owned and operated team of European car specialists serving the greater Metro Atlanta area. We started in 2004 as Mercedes Specialists of Dunwoody. In 2008, we changed the name to RS Motorwerks to reflect our Porsche® service in the greater Southeast. For more than a decade, our specialists have seen customers from as far away as Tennessee, South Carolina, and Florida.

RS Motorwerks’ lead Technician and Performance Specialist is John Herzler Jr. He is joined by his father (John Sr.), and Rob Wishen. Check out the RS Motorwerks bios to learn more about the staff’s background, training, and specializations that make them masters at their craft.

Despite our small size, we take pride in knowing that we are among the best performance shops in Atlanta. Our shop is extremely well equipped. You should only see the dealer in the event of warranty work or recall. Because most shops lack the tooling, training, and experience to perform high-level repairs, they prefer to replace components rather than repair or rebuild them, citing liability as the reason. At RS Motorwerks, we work with what you give us so that we can keep the car original, and the final bill within your budget. Our customers are our backbone. We do everything within our power to meet your repair needs and treat your vehicle as if it were ours. Our shop holds the advanced tools and equipment necessary to get the job done right the first time and every time.

We participate in the Bosch and Tire Rack Preferred Installer Programs. For our high-performance buffs, we offer Fabspeed and Stratmosphere stainless steel exhaust systems. We also offer Evolution Motor Sports and GT Transmission upgrades for our Porsche® clients as well as Renntech performance upgrades for Mercedes.

Whether you need Porsche® or Mercedes Benz repair or services, we have what it takes to meet your needs regardless of your budget.

Don’t just go to the service shop that is the closest to your home or the cheapest; expect nothing less than the highest-quality repairs and maintenance. The expert team at RS Motorwerks will give your car everything it needs. Contact us at 404-725-9926  or info@rsmotorwerks for more information about our Mercedes and Porsche® service in Atlanta, GA.
