Upgrades the basic dual-zone climate system to 3 or 4 independent zones, including rear passenger controls. Look for digital LCD temp readouts in the dash panel and rear console vents. Adds premium visual flair to the dashboard.
🚨 Avoid Retrofit Frauds:Always decode the VIN configuration rather than relying on visual trims. Sellers frequently install visual replicas (such as speaker covers or AMG body panels) on standard vehicles to charge a premium.
