The car is finished in Steel Grey Metallic (400) and is equipped with Shadowline trim and a Euro front bumper. The seller states the bumpers, side skirts, and lower headlight trim pieces have been refinished. Additional equipment includes xenon headlights, a glass sunroof, a trunk lid spoiler, and quad exhaust outlets. The rear Park Distance Control sensors are said to be unreliable. Paint meter readings taken around the body are provided at the end of the gallery.

The 19″ M cross-spoke Style 163M wheels are mounted with Falken Azenis RT660 tires that measure 245/35 up front and 275/30 out back. The car was factory equipped with Dynamic Stability Control (DSC), and braking is provided by Porsche 996 calipers over Euro CSL rotors with stainless steel lines at each corner. H&R sport springs and Koni shocks have been added, along with the following components:

  • Rogue Engineering rear shock mounts
  • Ground Control front adjustable street camber plates
  • ECS Tuning adjustable rear control arms
  • Turner Motorsports front control arm bushings
  • Lemforder front control arms, tie rods, and ball joints
  • Lemforder rear trailing arm upper and lower ball joints
  • Vorshlag low-profile steering shaft
  • UUC sway bars
  • Condor trailing arm, subframe, and differential bushings

The power-adjustable front sport seats are upholstered in Cinnamon Nappa leather and were refurbished under current ownership. The pillar covers were also replaced and the center armrest was reupholstered in black with M tri-color stitching, which extends to the leather shift boot and parking brake boot. WeatherTech liners are fitted in the footwells, and additional sound deadening has reportedly been added below the carpets. The Alpine touchscreen head unit is wired to an Alpine four-channel amplifier, a JBL 8″ powered subwoofer under the driver’s seat, and Bavarian Sound Works speakers. The heated seats, cruise control, and traction control are inoperative.


The 7.0L LS7 V8 crate engine was installed in June 2021 and features a wet sump conversion that utilizes a Holley oil pan, a Melling high-pressure oil pump, and a PowerBond Race Performance harmonic damper. Cooling is through a Koyorad aluminum radiator with a SPAL electric fan and a Mishimoto adjustable fan controller. The exhaust system incorporates Vorshlag long tube headers and 3″ stainless steel pipes with Borla ProXS mufflers and a Magnaflow X-pipe, catalytic converters, and resonators. Additional engine components include the following parts:

  • American Heritage Performance cylinder heads
  • MSD Atomic AirForce intake manifold
  • ARP hardware
  • Cam Motion Stage 2 camshaft
  • Improved Racing crank scraper and windage tray
  • Johnson 2110 hydraulic roller lifters
  • Manton custom length pushrods
  • CHE rocker arm trunnion bushings
  • Wiring Specialties harnesses and CANBUS adapter
  • High-torque starter
  • CTS-V front accessory drive kit
  • Mighty Mouse catch can
  • Aeromotive in-tank fuel pump
  • Fuel Lab fuel pressure regulator
  • Weldon 10-micron stainless steel fuel filter

Power is routed to the rear wheels via a Tremec T56 Magnum six-speed manual transmission, a Vorshlag aluminum driveshaft, and a limited-slip differential, which was rebuilt with Racing Diffs components. A Tilton twin disc clutch, flywheel, and throw out bearing were also added. A Turner Motorsports front subframe reinforcement kit and Practical Performance rear subframe kit were installed in 2020.
