When preparing to purchase a used car, it's essential to have a thorough conversation with the seller, whether they are an individual or a dealership. Here's a list of crucial questions to ask over the phone before scheduling a visit:

　　Accident history and damage: Has the vehicle ever been involved in an accident? If so, what kind of damage was sustained, and has it been professionally repaired?

　　Scratches, dents, and stone chips: Are there any scratches, dents, or visible signs of stone chips on the bodywork?

　　Number of previous owners: How many owners has the car had? This can affect its condition and maintenance history.

　　Service records: Is the car fully documented with a complete service history? Have all services been performed as per the manufacturer's recommendations, and is there a detailed logbook?

　　Mileage verification: Can you confirm that the stated mileage corresponds to the entries in the service book?

　　Past repairs and invoices: What major repairs has the car undergone, and do you have the corresponding invoices? Are there any active warranties or guarantees on these repairs?

　　Wear and tear on key components: Are there any known issues with wear on bearings, steering, or axle parts? Does the car track straight when driving?

　　Transmission: Does the transmission shift smoothly without any grinding or hesitation?

　　Engine oil leaks: Is the engine losing oil, indicated by oil stains on the ground?

　　Rust presence: Are there any rust spots on the car, both externally and under the chassis?

　　Interior condition: What is the overall state of the interior, including seats (are they worn or torn?), carpets, and dashboard materials?

　　Electrical systems: Do all electrical features function correctly, such as power windows, sunroof, windshield wipers, air conditioning, and infotainment system?

　　Registration status: Is the vehicle currently registered and available for a test drive?

　　Avoid discussing specific pricing over the phone; instead, use this initial conversation to gather information about the car's condition. Armed with knowledge of any defects or issues, you'll be better prepared to negotiate a fair price during your inspection and test drive. By asking these pointed questions, you demonstrate to the seller that you are a serious buyer who has done their due diligence.
