All vehicles at Tianyuan Dachangxing Luxury Cars support third-party inspection. 1. Our vehicles sell quickly; we only have about 10 of the same model available (only 1 is displayed on the website). For test drives, please contact our sales staff in advance to verify vehicle availability to avoid inconvenience. 2. Our company mainly deals in mid-to-high-end used cars and luxury cars, offering services such as purchase and sale, trade-in, consignment, appraisal, car insurance, financial services, and vehicle transfer. 3. We maintain a stock of over 1200 vehicles year-round (actual photos of the vehicles). More premium cars are available for selection in our online store. 4. Worry-free after-sales service: one-year/20,000 km warranty (based on the original warranty). Transparent vehicle condition, premium service, and worry-free consumption. (For out-of-town customers who successfully purchase a vehicle at our store, we will reimburse one-way personal airfare and overnight accommodation expenses, with the ultimate ownership belonging to our company.)
Obtaining precise internal resistance at different SOC levels requires disassembling the battery pack and connecting it to a professional charge-discharge cabinet for several days of cycling tests. This is beyond the scope of non-destructive used car inspections; we only provide real-time estimated internal resistance data based on OBD port readings.
Air suspension is very delicate. If, after the vehicle has been stationary for about 12 hours, the height on one side of the vehicle drops more than 1.5 cm when measured from the wheel arch to the tire, we will determine that there is a slight air leak in the air spring or distribution valve on that side and warn you of the high subsequent repair costs.
To prevent intermittent failures due to aging of the resistance wire, we will start the engine and set the seat heating/ventilation to maximum for at least 5 minutes, confirming significant temperature changes or airflow output in the cushion and backrest using an infrared thermometer or body sensor.
