What are the four key points to check when inspecting a used car's condition?

The four key points to check when inspecting a used car's condition are verifying documentation, checking for accident history, identifying odometer rollback, and detecting water damage. Below are detailed explanations of these four key aspects: 1. Key details: Each inspection point has its specific focus. Document verification mainly examines the vehicle's purchase invoice and tax payment certificate, while accident inspection involves checking the car's paint surface. Odometer rollback detection verifies mileage accuracy, and water damage inspection looks for musty odors and rust inside the vehicle. 2. Used car sources introduction: Vehicles mainly come from private direct purchases and institutional purchases.

When buying a used car, I always focus on four key points based on personal experience. First, the exterior must not be overlooked—carefully check for scratches or uneven paintwork, which may indicate accident repairs or rust issues, and feel the edges and gaps for smoothness with your hands. Second, engine compartment inspection is essential—start the car to listen for smooth engine sounds and check for oil or coolant leaks to avoid future repair hassles. Third, thoroughly assess the interior—examine seat wear and test dashboard electronics like the AC and audio system to avoid being misled by superficial cleanliness. Fourth, always conduct a road test—drive to evaluate acceleration, braking distance, steering precision, and suspension stability. Combining these checks gives a good sense of the car's condition. I also advise buyers to bring an OBD scanner to review maintenance records and ask sellers about driving habits for extra assurance.

When it comes to evaluating a used car's condition, I instinctively focus on four key aspects. For the exterior, carefully inspect the body structure, paying attention to any deformities in the front/rear bumpers and headlight mounting positions—these reveal collision history. Then examine the engine and powertrain: don't just check for oil leaks, but also listen for abnormal sound variations during neutral-gear acceleration/deceleration. Regarding the interior, go beyond seat stains—test functional details like window operation and AC airflow. Most crucially, always conduct a test drive to assess cornering over bumps, brake responsiveness, and overall handling safety. Additionally, never overlook tire tread wear as it impacts performance. Combining these evaluations helps avoid costly mistakes when purchasing a problematic vehicle.

When buying a car, I focus on four key areas: first, check the exterior for any accident marks or repair points; second, inspect the engine for smooth startup without strange noises or oil leaks; third, test the interior, seats, and electrical functions to ensure they're intact; fourth, take it for a drive to feel the smoothness of the ride and the stability of the brakes. Body rust or frame deformation is a major red flag, excessive startup noise may indicate internal issues, worn-out interiors suggest heavy use, and a test drive can reveal hidden faults. Getting these right usually means the car is reliable.
