At Winkler Automotive Service Center, We Turn Wrenches Happily!

The Next 30 Years

In December 2015, Winkler Automotive Service Center changed ownership.After more than 30 years at the helm, cultivating and growing a highly reputable business, George Winkler understood that the automotive industry had entered the midst of a revolution. During his time, George saw the fuel injection take over the carbureted systems, and the ever increasing reach of digital systems in cars. Today, cars are being redefined on a yearly basis.

The average car today is a complex assortment of computers talking over a network, constantly monitoring and adjusting a myriad of parameters to ensure the proper function of all systems, from engine to transmission to the entertainment center.

Properly diagnosing a car today requires an expert mechanical grasp as well as a deep understanding of the various information technology systems imbedded in each car.

The ability to plug into a car and listen to and understand the streams of data coming from it is critical for the successful repair of your vehicle.

The new owner, Karim Morsli, a long time enthusiast of cars and their information technology systems brings a deep understanding of the intricate mixture of mechanical and digital systems found in today’s vehicles.

About the Owner, Karim Morsli

Karim Morsli

An engineer by trade who has worked in the oil fields and information technology industry, Karim is passionate about the new direction the automotive industry is taking, and in particular the critical role independent service centers will need to evolve into to ensure all present and future car owners will have the choice of where to have their vehicle serviced besides the dealership.

Karim is an innovator who works on multiple levels within the industry (education and legislative) to ensure his service center and others like his are ready for the challenges ahead. Always one to practice an open door approach, he is always willing to teach and share his knowledge, and is also an avid learner!

It is under his watchful innovative guidance that Winkler automotive Service Center will continue to successfully service the Gaithersburg community, just as it has for the past 34 years, and we hope you will join us on this journey.


Mary Ditman - Service Manager


Mary Ditman

Mary attributes her interest in cars to her father, who is a retired master Chrysler technician and often had her around classics like his 1968 Plymouth Barracuda, or the 1972 Oldsmobile Cutlass that Mary drove as her first car.

Following her father’s footsteps, Mary worked hands-on as an apprentice technician for a year before realizing she preferred a more customer service related position, and thus became a service advisor. Ever since then, making sure cars are safe and well-maintained has become a passion for her. She is excited to be working at Winkler Automotive, since she has found a team of people who care about the cars they work on as much as she does.
