Inside, the shortened cabin retains carbon bucket seats upholstered in red and black leather, plus a small portion of the rear bench for cargo.
Additional carbon fiber inserts adorn the dashboard, door cards, center console, and steering wheel.
Under the hood, the twin-turbo 3.0-liter six-cylinder engine has been upgraded with new turbochargers, a carbon fiber intake, a new exhaust, and a recalibrated ECU.
These modifications mean it produces more than the standard 503 hp (375 kW / 510 PS), with power sent to all four wheels via an eight-speed automatic and xDrive AWD.
The odometer shows just 8,000 miles (12,875 km), and the vehicle is reported to be in excellent condition.
The high bidder appears to be Carrio Motor Cars, a Florida exotic car dealership, suggesting the M4 Maloo may soon resurface for sale at a higher price.
