Prior Design wanted to recreate Mercedes’s popular ‘Black Edition’ variation for the SL Roadster on a CL C216 model.
It is up to you to decide weather or not they succeeded, but from what we see in these photos they seem to have done a good job in making the CL much more muscular and aggressive.
The main enhancement through which this was achieved is its bulky wide body kit that contains front mud wings, wider rear body panels and redesigned side skirts. The Prior Mercedes CL Black Edition has also received a ‘decent roof scoop’, a sculpted bonnet along with new bumpers and a set of 20 inch alloy rims.
For an even more customised look, Prior can fit the Mercedes CL with several carbon parts supplied on demand as well as with individual tailor-made equipment.
