The W221 S Class has been an integral part of the success of MEC Design. One of the first vehicles to receive the full MEC Design make over it is still selling well despite the release of the newer W222 model. As with all MEC Design tuning you are able to choose from individual parts or have your complete vehicle refined with a range of external parts such as their aerodynamic bodykit, great sounding exhausts and amazing looking wheels. The interior is also able to benefit from MEC Designs years of experience with a range of elegant fitments including steering wheel and solid wood or carbon fibre enhancements and quality floor mats.
