Jason Schwegmann

Chief Executive Officer

My whole life I have been involved in Custom and or Performance cars. My career started in 1990, when I was 13 years old. In 1992, I bought my first American Muscle car and began to restore it. This highlighted the intensity of my desired career path. Many technical aspects were needed to complete the project, and so my career began.

Over the years, I worked with the best in the industry and learned and developed the skills required to build and restore a muscle car. The purpose of my ongoing pursuit for knowledge and skills led to a network fibre being created which, enabled me to be apart of the biggest Executive Restoration Workshop in the southern hemisphere.

I continued my work on bespoke Signature Series cars accumulating multiple award winning cars. Many of my clients built cars as an investment opportunity. I was focusing on pushing the limits of my creative knowledge. I was building “World Firsts”

I have managed to accumulate over 20 years of hands-on working knowledge of the Performance Custom Car markets, in multiple trades. I was born to do this and doing anything other than performance cars just feels like starvation.

My passion for cars was sparked by helping my grandfather work on his beloved 1972 VW pick up truck at the age of 10. It continued on with getting my first car, a Nissan Altima, 2 weeks before receiving my drivers license. Since then i knew I couldn’t have a stock car and began modifying it and to this day its still a work in progress along with the other 2 cars I have acquired over the years, a 1983 Datsun 280zx and a 1986 Nissan Skyline.

My first job was at a classic car restoration shop as a helper, and I quickly learned new skills and techniques on a daily basis. After a couple years of doing mechanical and electrical work, in my desire to become a custom car builder, I decided to move on and start working at another restoration shop but this time in the body and paint department. Went on from learning the basics of body work to doing an overall paint job. And that brought me a step closer to achieving the goal of becoming a custom car builder.

Along the way, i was lucky enough to have met Jason and have worked by his side. Building cars with him is been an experience like no other and greatly helped improve my skills further.

From a very young age I incorporated discipline and focus in my persuite for physical fitness and business alike, through excessive hard work I was able to achieve multiple awards in strong man and world bench press competitions, I have represented my country multiple times in sports and have continued to manage a well balanced and healthy lifestyle.

I have always enjoyed my car collections and throughout the years I have been able to experience the process of getting involved in my own design and build phases, allowing me to enjoy the creative process hands on. Jason and I met approximately 12 years ago during a build of one of my projects and we developed a very deep and close friendship, as Signature Series grew the opportunity was obvious and the joining of Signature Series felt completely natural. I am focused on guiding the future client through this amazing process of self controlled automotive design and fabrication.

Since I can remember I have always had an interest in golden oldies, fast cars, and roaring engines. They gave me goosebumps and a feeling of excitement as soon as the engine comes to life. Sometimes taking me back to icecream Sundays and good old times.

I have explored the financial industry for more than 15years, accumulating my short term, long term, financial, investment, and wealth management qualifications. This has taught me the importance of building trustworthy relations with clients. Managing their portfolios, I do understand the need for finely detailed planning, perfection, and achieving goals with lasting relations and ensuring their best interest will always be at heart.

Joining Signature Series Supercars has given the opportunity to combine these dynamic worlds and making it possible for you to have your dream collection worth investing and seeing quick fast, effortlessly returns.

International Event Co-Ordinator

The Events and Entertainment Industries have always been a passion of mine. After I matriculated, I studied Audio and Video Production and worked in Video Production in the USA in 2007. Upon returning to South Africa in 2008, I started my own Events and Entertainment Company. We specialized mostly in Fitness and Corporate Events, and also worked with a lot of celebrities in the entertainment industry. In 2018, I received my South African Protea Colours for Team Management. In 2019 I opened my own Fitness, Events and Entertainment Academy with the best accreditation in Africa.

I have several annual events I have grown from nothing to being the biggest and most prestigious in South Africa. That is my aim for the Signature Series Supercar Events I will be organizing all over the world.

Signature series is giving me the opportunity to broaden my horizons, to take all the knowledge and experience I have accumulated over the years and excel beyond the borders of Africa. I am extremely excited to be a part of this team.

I am a very driven and creative person who is extremely passionate about what I do. No challenge is too big and no goal is impossible to achieve.

IT Development & Support

In the past 18 years I have seen my career grow and diversify over this time period. I started my corporate working career at First National Bank (FNB) within their marketing department. I later moved into the IT sector, fulfilling the role as a MIS Analyst. This was where my career really started growing and I discovered my interest in databases, and web development. This interest has taken my career to where it is today, a Database Administrator and Business Intelligence Analyst.

Outside of work, enjoy spending most of my time outdoors. It was around 2012 when I discovered trail running, and over the past years it has become one of, if not, my favorite past time. Towards the end of 2018, I decided to start writing my own blog, “Trail Hogs”, so that I could share some of my experiences and learnings with others who may also want to explore the adventurous outdoor world of Trail Running. What else would you find me doing in my spare time? Some of my other interests include woodworking, Geocaching, collecting Collector's Movie Boxsets.
