Exterior: Black. The maintenance of this car is quite good. The exterior is clean and sleek, and the interior buttons still have a high-quality feel. During the road test, the power is still readily available when needed, and the chassis integrity is excellent, with no loose feeling when passing over bumps. As one of the two global giants in the business and executive car segment, the "BMW 7" has a different positioning from the Mercedes-Benz S. The Mercedes-Benz S is more oriented towards official and government use, while the BMW 7 is more targeted at celebrities, artists, technology entrepreneurs, and others with social influence. In terms of brand image, the Mercedes-Benz S is more low-key and steady, while the BMW 730 is more fashionable and distinctive. The exterior of this car exudes a very aggressive and imposing presence. I am extremely satisfied with the interior craftsmanship. The center console is entirely covered with soft leather, making it appear very high-end. The rear space is spacious enough, and the handling remains consistent with BMW's usual characteristics, with precise steering. As a business car, it is not used frequently and is taken care of very well.
