It is necessary to install rain visors on sedans, as they serve the following purposes: 1. Rain visors are installed above the car's rearview mirrors and windows to block rain. 2. The rain visors installed above the rearview mirrors protect them from getting blurred by rain. 3. Another rain visor installed on the car window protects the driver and passengers. 4. During rainy days, the window can be slightly lowered to form a "canopy" with the rain visor, allowing ventilation without getting wet. Precautions for installing rain visors are as follows: 1. The color of the rain visor should not be too dark, as it may affect the driver's vision. 2. The installed rain visors should match the car model's appearance; otherwise, they may affect the overall aesthetic. 3. It is advisable to choose rain visors made of acrylic material for a longer lifespan.

I've been driving for over ten years and have always used rain guards, which I find quite necessary for sedans. When driving in the rain, they effectively prevent rainwater from flowing into the car, making it much easier to crack the windows for ventilation, especially during traffic jams or when smoking, without getting wet. In summer, you can take a break in the car without turning on the AC, saving some fuel costs. Installation isn't complicated either; you can buy a set online for just a few dozen bucks and do it yourself. The downside is a bit of wind noise at higher speeds, but it doesn't affect safety. Overall, they're highly practical, and I recommend installing them, especially for those in rainy areas or who frequently drive with windows down.

As a new car owner on a budget, I've considered whether rain guards are worth installing: they're inexpensive at just a few dozen yuan, can prevent rainwater from entering the car and protect the interior, and allow for window ventilation to slightly reduce AC usage and save a bit of fuel. However, aesthetically, they might make the car look less attractive; after rain, water stains can easily remain and affect visibility. Personally, I think if you live in a rainy area or frequently drive with windows open, it's necessary to install them; in places with less rain or if you rarely go out, you might as well skip them to save hassle and money. My advice is to decide based on personal habits and environment, and not blindly follow trends.

I value the appearance and safety of sedans, and I don't think rain guards are necessary. They disrupt the aerodynamic design, increase wind resistance and noise; in rainy weather, the actual impact of rainwater is minimal, as the factory sealing is excellent. Unless you live in a heavy rain area or always drive with windows open, they are purely redundant and add cleaning hassles. From a safety perspective, wind noise interference is noticeable at high speeds. Keeping the car in its original state is better to avoid maintenance trivialities.
