You and three others have decided to form a Cars and Coffee Quartet (like a Barbershop Quartet but with cars). You as the lead over the group need to decide which four vehicles will join forces to serenade the crowds with excillerating exhaust, engine, and induction notes, wailing tires, whistles, drones, alarms, horns, and any other sweet noises you can coordinate into a concerto for four vehicles.

No other stipulations so have at it and as always, enjoy yo’selves!
