How Long Does It Take to Pick Up a Car When Buying from a Car Trade Company?

You can pick up the car immediately if it's in stock; otherwise, it depends on the availability of the car. Car Trade Company: They are secondary car dealers but not officially authorized distributors. Car trade companies sell cars, usually purchasing them at lower prices from 4S stores and then selling them at a markup. Due to almost negligible storefront and inventory costs, car trade companies still hold certain advantages. The differences between car trade companies and 4S stores are as follows: Most car sales companies offer a wide variety of car brands and models, but the specific models and configurations for each brand may not be very comprehensive. In terms of service and environment: Because the staff at 4S stores undergo systematic training, the service quality is generally better than that of car sales companies. Moreover, 4S stores are invested and constructed by dealers according to the standards set by car manufacturers, featuring unified designs inside and outside the store, with investments often exceeding tens of millions, making them luxurious, grand, and comfortable. 4S stores also have dedicated customer rest areas, entertainment areas, etc., with more complete supporting facilities compared to car sales companies. In terms of after-sales service: At 4S stores, you can enjoy car after-sales services, with quality assurance. In contrast, most car sales companies offer limited or no warranty services, which are generally less comprehensive than those at 4S stores.

How Many Points per Question in Subject Four?

According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," the road driving skills and safety and civilized driving common sense test in Subject Three deducts 2 points for each wrong answer, with a maximum of 5 wrong answers allowed before failing. The full score is 100 points. Questions 1-10 are true/false questions; questions 11-40 are single-choice questions; and questions 41-50 are multiple-choice questions. The test includes question types such as image analysis, animated case studies, and text descriptions. The scope of Subject Four covers driving common sense under adverse weather and complex road conditions; identification of common traffic signs, markings, and hand signals; accident rescue and common hazardous material handling knowledge; comprehensive judgment of illegal behaviors and case analysis; emergency avoidance common sense; safe driving knowledge; and driving ethics and civilized driving common sense. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," Subjects One and Four have no limit on the number of exam attempts. If the first attempt on the same day is not passed, an immediate retake is allowed. If it is still not passed, a new appointment is required, and no retake fee is charged. However, it should be noted that the validity period of the driving skills test permit is three years. If the applicant does not complete the test within the validity period, the passed subject results will be invalidated. Subject Four, also known as the Subject Four theory test or driver theory test, is part of the motor vehicle driver's license assessment. After the implementation of the Ministry of Public Security's Order No. 123, Subject Three was divided into two parts: the road test and the safety and civilized driving common sense test. Subject Four is the colloquial term for the latter, not a separate subject. Since this test is conducted after Subject Three, it is commonly referred to as the Subject Four test. Officially, there is no Subject Four. The safety and civilized driving common sense test is conducted after Subject Three. Subject Four Exam Notes: Exam Duration: The exam lasts 45 minutes. If 12 points (6 questions) are lost during the test, the exam will be terminated. Number of Questions: Depending on the type of driver's license, 50 questions are randomly selected from the corresponding Subject Four question bank, with each question worth 2 points. Question Types: The exam includes single-choice questions (including true/false questions) and multiple-choice questions. The first 45 questions are single-choice, and the last 5 are multiple-choice. The test also includes animated questions, image-based questions, scenario identification questions, and text-based questions. Retake Notes: If Subject Four is not passed, only Subject Four needs to be retaken. The driving school will schedule the retake, with no limit on the number of retakes. No retake fee is required for Subject Four. There are three subjects in the driver's license test: Subject One, Subject Two, and Subject Three. Subject Three is divided into two parts. Subject One refers to the test on road traffic safety laws, regulations, and related knowledge; Subject Two refers to the field driving skills test; and Subject Three refers to the road driving skills and safety and civilized driving common sense test.

Is it necessary to replace traditional wiper blades with beam blades?

Traditional wiper blades can be replaced with beam blades, but this depends on the pressure of the wiper arm on your vehicle. For example, some Japanese cars have lower wiper arm pressure, and using beam blades may result in poor wiping performance over time. The differences between the two are as follows: Different support points: Traditional wiper blades have multiple support points that are evenly distributed, while beam blades have only a single central support point, maintaining a smooth curvature. Noise differences: Beam blades have a much lower wind resistance coefficient. When used at high speeds, they operate quietly, with almost no audible noise from the wipers. In contrast, traditional wiper blades, due to their multiple frames and larger occupied space, produce noticeable noise when moving at high speeds. Other aspects: Beam blades are easier to install and less prone to damage, but they are more expensive. Traditional wiper blades, however, are better at removing larger debris.

Why Can't the Right Rearview Mirror See the Rear Wheel?

The reason the right rearview mirror cannot see the rear wheel is due to improper adjustment of the mirror or inherent issues with the vehicle itself. Rearview mirrors are used to help drivers observe the rear road conditions and the surroundings of the car during reversing. All vehicles are equipped with rearview mirrors. Improper adjustment of the rearview mirror: First, confirm whether there are obstacles around the car, whether the reversing space is sufficient, and whether the distance and turning angle are adequate. Then, adjust the rearview mirror slightly downward to see both taillights for reversing operations. Inherent issues with the vehicle: The wheelbase of the car may be too small, or the waistline of an SUV may protrude more than that of a regular car model. A small auxiliary mirror can be installed on the rearview mirror, positioned to see the tires, allowing visibility of the tire position during reversing. Alternatively, installing a reversing camera can provide a clear view of the rear.

What Causes Constant Engine Shaking?

Constant engine shaking can be caused by a dirty air filter, broken high-voltage wires, worn spark plugs, low idle speed, or clogged fuel injectors. The details are as follows: Dirty Air Filter: The air filter is designed to protect the engine and reduce wear. It should generally be replaced every 10,000 kilometers. If not replaced in time, insufficient air intake can lead to low idle speed, causing the engine to shake. Simply replacing the filter can resolve this issue. Broken High-Voltage Wires: Broken high-voltage wires refer to the interruption of the wire core, which can affect ignition and cause engine shaking. Use a multimeter to measure the resistance and replace the wire with significantly higher resistance. Spark Plug Lifespan: Spark plugs have a limited lifespan. After 30,000-40,000 kilometers, their ignition efficiency noticeably decreases, which can affect ignition. This is a common issue, and replacing all spark plugs can solve the problem. Low Idle Speed: The engine idle speed is preset in the car's computer. If the RPM drops below a certain range, the car's computer will automatically adjust it. If the idle speed is too low and causes shaking, it means it has exceeded the computer's control range. Some cars have an adjustment screw on the throttle body to regulate idle speed, while others do not. For such cars, check the idle control valve, throttle body, air flow meter, vacuum sensor, or adjust the ignition timing (for cars with distributors) to increase idle speed. Low coolant temperature can also cause low idle speed, so check and replace the thermostat if necessary. Clogged Fuel Injectors: The fuel injector in an EFI car is a critical component for fuel injection and has a long lifespan, often reaching hundreds of thousands of kilometers. However, deposits in gasoline can clog the injector nozzles, causing uneven fuel injection among the injectors. This leads to inconsistent cylinder operation and engine shaking. The solution is to remove and clean the injectors.

Does Scratches on Headlights Have Any Impact?

Scratches on the car headlight cover only affect the appearance and have little impact on road illumination. Causes of Headlight Scratches: It may be due to accidental bumps while driving, scratches from pedestrians or objects while parking, or small stones kicked up during driving. Minor scratches won't affect the vehicle's driving illumination, but if bothered, the cover can be replaced with a new one. Function of Car Headlights: Car headlights, also known as car front lights or LED daytime running lights, serve as the eyes of the car. They not only relate to the owner's external image but are also closely linked to safe driving at night or under bad weather conditions. The use and maintenance of car lights should not be overlooked.
