very good
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.)
Once the car system (especially in a closed ecosystem) undergoes a major version upgrade, its bootloader is usually locked, preventing downgrades. If this happens, there is basically no solution in an overseas environment. Therefore, we strongly warn: do not blindly insert a USB drive to upgrade while offline.
We repeatedly confirm and emphasize to buyers before sale: after leaving mainland China, most Chinese smart electric vehicle ecosystems (such as cloud voice assistants, online maps, OTA updates) will be permanently offline. You are purchasing a hardware platform with excellent mechanical quality and a three-electric system; please use it as a "standalone" vehicle. Do not trust false promises from other channels claiming "perfect overseas unlocking and continuous official OTA updates."
We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).
