There are some bold Mercedes-Benz owners out there, but this one takes the cake for the most wild DIY ever. And to make matters even more outrageous, the owner (Brent Khelawan) decided to super-tune a 2006 CLS500. We mean, the CLS is already great to begin with. The moment it was released, Mercedes-Benz fans and owners alike were caught off guard. The CLS totally disarmed even the keenest of critics with its sheer majestic beauty, coupled with awesome power and state-of-the-art automotive technology. Of course, you would not expect anything less from the company that built it. But it seems Brent wasn’t satisfied with his ride being in stock form, so he decided to take a few things out and put some cool stuff in.

Perhaps the wildest item in the list of outrageous modifications is the motor swap—a supercharged AMG 5.5-liter M113K engine replacing the stock CLS powerplant. This engine came from a 2005 model E55, so you could imagine what great lengths Brent went through in order to make this thing work with his CLS. Of course, big names in the auto industry were all doubtful that Brent would be able to pull it off. But he did, and so he gives credit to a couple of friends, Rudy Compart of Accelerated Industries and Jake of Herb Gordon Mercedes, for helping him piece things together seamlessly.

Take note folks, this is a show car that sees competition with other Euros mostly on the east coast. Motor Trend even made a deal with Brent to sponsor his car’s appearance at the Baltimore Auto Show. So yes, this car is smoking.
