Cameron Douglass loves station wagons.

His penchant for “long roof” cars is renowned in the car collecting community and it is exemplified in his remarkable collection of superb shooting brakes of various American and German origin—which includes a variety of Mercedes Benz haulers. And haul they do—as each has been massaged to varying degrees to provide transport of multiple people and their goods at a very rapid pace. But of all of his hauling ass haulers, the ‘star of the fleet’ is this rare (only 200 made, and under 50 shipped Stateside) R63 triple obsidian beauty.

As an executive with the renowned high-performance Optima Batteries company, Cameron is a person committed to performance and quality…and he has applied his passion for those qualities on this particular R63. Investing considerable time and nearly doubling the original cost of this R63 Cameron teamed with the famed Weistec 3-pointed star tuners to create what is arguably the most handsome and fastest R63 on the planet. Period.

The 6.2L M156 V8 was carefully disassembled and examined by factory tutored Mercedes-Benz techs at Weistec Engineering and then fitted with: ARP head bolts, SLS valve lifter buckets, and a Stage 2 twin-screw Weistec Supercharger System, which includes a Weistec custom intercooler, aluminum lower manifold and throttle body inlet, high-capacity fuel injectors, an RoW airbox and ECU engine tunes. Weistec Engineering long tube headers dump into high-flow catalytic converters and a custom mid-section that mates to the factory cans. The original 503 horse herd now numbers near 750 anxious ponies.

The M158’s prodigious power is delivered through a Weistec tuned 7speed box and then on to custom 21″ two-piece machined billet aluminum wheels made from a proportionally correct 3D scan of an original AMG Monoblock rims. Michelin Pilot Super Sport hides are fitted on these handsome wheels and the whole assembly’s considerable speed is tempered by nickel-coated billet six-piston Brembo calipers with drilled and vented two-piece rotors. Those are some proper brakes on this shooting brake.

The factory suspension can be lowered via a module that utilizes the DIC buttons on the steering wheel to make sure that hauling is properly hunkered down at speed.

This performance platform is wrapped in factory 040U black hue and optional factory rear fender lip flares have been added. Attention to detail continues with front license plate mounting holes filled and the bumper disassembled and repainted. The subframe, underbody panels, and heat shielding were disassembled, inspected, and cleaned during the engine removal process.

Those plying the sun-kissed highways and byways of Orange County know that when this noir R63 shows up in their rear-view mirror they are well advised to move into the right lane and let this hauler pass by at considerable speed and aplomb—with a smiling Cameron Douglass at the wheel.

  • I guess if you gotta drive a minivan, might as well be this one.
