Premium Aluminum Trim = Simple Elegance
A gear knob is one piece of trim which is touched every time a vehicle is put in motion. It makes sense that the expectation is for the gear knob to match the look and feel of the vehicle that it is directing.
Brushed aluminum is a common foundation to build from when determining the look for premium trim. The complex form of gear knob inserts highlight the metal characteristics of the aluminum. This provides opportunity to maximize perceived value for the brand.
