The interior was my job. Mark let me do what I wanted. From carpet to headliner. The center console is made of mdf. The Holley Dash has a 3D printed surround with a black vinyl wrap and carbon fiber trim. The Shifter knob is a 3D printed test piece that's now permanent. We used the TrailBlaze steering wheel. The buttons on the wheel control a custom heater/defroster. The wiper controls work too. A custom BCM was made using an Arduino to control the wipers and the heater.
