Design a futuristic Mercedes Benz and eco-friendly dream car with a unique and organic shape. The car should blend advanced technology with natural aesthetics. The exterior should have fluid, aerodynamic lines that change colors based on the environment. The car's wheels should float above the ground using magnetic levitation. Inside, the car should have a minimalist design with holographic screens that display information and controls. The seats should be made of memory-like material, offering comfort and a floating sensation. The roof should be a smart glass that adjusts transparency depending on the surroundings. The car should be powered by a self-sustaining electric motor with solar panels integrated into the body. It should have autonomous driving, a soundless driving mode, and the ability to adapt to different environments. The materials should be eco-friendly, recyclable, and biodegradable.
