Paint and Body

The M491 option was first introduced in 1984 and features front and rear spoilers from the contemporary 911 Turbo as well as wider front and rear fenders. The car is finished in Black and features headlight washers, front and rear fog lights, and black stone guards ahead of the rear wheel openings along with a power-operated sunroof, heated power-adjustable side mirrors, and a Turbo rear badge. Paint meter readings are shown in the photo gallery and indicate majority of the paint to be original.

Interior

The power-adjustable front sport seats are upholstered in Black leather, and the dashboard, door panels, and folding rear seats are trimmed to match. A Porsche Classic stereo has been added, and additional appointments include air conditioning, cruise control, and power windows.  Fuse panels were serviced with new fuses in June 2024.

The leather-wrapped steering wheel frames VDO instrumentation consisting of a central tachometer with a 6,300-rpm redline as well as a 170-mph speedometer, a quartz clock, and gauges for oil level, oil pressure, oil temperature, and fuel level. The six-digit odometer shows 103k miles.
