Could you imagine working with design teams to help fulfill a vision of custom cars to put on display on behalf of Chevrolet Performance? John McKernan is one of them. Earlier this year, we checked in with the Program Manager for Specialty Show Vehicles with Chevrolet Performance to discuss his automotive background and the pressures of building show vehicles for one of the largest companies in the world.
