What is the difference between auto trading companies and 4S stores?

The differences between auto trading companies and 4S stores: 1. A 4S store is an authorized dealer of a brand; auto trading companies do not have manufacturer certification. (1) A 4S store is a sales outlet that integrates car sales, maintenance, parts, and information services. It can only sell a single brand of cars specially authorized by the manufacturer, and the manufacturer also requires unified design requirements for the store's interior and exterior. (2) Auto trading companies are not controlled by manufacturers and do not have vehicles for sale themselves. They source vehicles from wherever they are cheapest across the country, meaning auto trading companies have a wide variety of vehicle sources. 2. Auto trading companies offer lower prices, but the quality of the cars cannot be guaranteed. The prices offered by auto trading companies are cheaper than those of 4S stores because they source vehicles from the cheapest locations nationwide. This results in uncertainty regarding the source and quality of the vehicles, with some auto trading companies even selling inventory cars or problematic vehicles.

How Often Should the Clutch Disc Be Replaced?

The clutch disc should be replaced every 50,000 to 60,000 kilometers. Methods to reduce clutch disc wear include: 1. Do not depress the clutch pedal unnecessarily when not shifting gears; 2. When decelerating, avoid depressing the clutch pedal too early. Wait until the vehicle speed drops to a reasonable range before pressing the clutch pedal to minimize clutch idling; 3. When parking, shift to neutral and release the clutch pedal to avoid adding unnecessary burden to the clutch; 4. Start the vehicle in first gear to utilize the initial torque, reducing clutch overload. Additional Information: Although the clutch disc withstands extremely high working pressure, its strong resistance to wear and high temperatures means its replacement cycle is not short. Symptoms indicating severe clutch disc wear and the need for replacement include: lack of acceleration power during driving, the engine revs increasing without a corresponding increase in vehicle speed, clutch slippage, and even the smell of burning.

How to Deal with Scratches on a Car?

Methods for dealing with scratches on a car mainly include: 1. Scuffs. Apply a coating agent that matches the car body to the scratched area. The coating agent can be applied once, twice, or three times. The more times it is applied, the cleaner it will look, but it is also important to ensure uniform treatment across the entire car body. 2. Minor scratches. If the rust is not severe, start by using very fine water sandpaper dipped in water to gently remove the rust spots. Avoid sanding randomly; instead, sand in a straight line in the same direction. Once completely clean, apply a layer of primer. For new scratches, clean the area and apply primer directly. If the vehicle comes with a small can of original factory paint, wait for the primer to dry, then sand it smooth with water sandpaper and apply the original factory paint over the primer. If original factory paint is not available, purchase a touch-up pen and use it for coloring. 3. Small scratches. If it is just a very shallow scratch on the surface paint, immediately use a compound to treat it. Wipe in a straight line. Once the scratch disappears, use a finer compound to wipe again and then apply wax.
