The interior was freshly equipped with leather turbo sport seats and a Momo Alcantara steering wheel with red stitching and a matching shift knob cover, along with a subwoofer installed under the passenger seat. More recently, AP Car Design fitted this 911 with Speedline 3.6-style wheels custom designed for narrow body cars, adding an additional layer of period correct beauty.
