1. All vehicles at Dah Chong Hong Luxury Cars support third-party inspection. Our vehicles sell quickly; we only have about 10 of each 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 1500 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 vehicle's warranty). Transparent vehicle condition, premium service, and worry-free consumption. 5. Dah Chong Hong offers a 3-day return policy, a 7-day exchange policy, and lifetime free oil changes for vehicles on the second floor! (Subject to the vehicle purchase contract.) (For out-of-town customers who successfully purchase a vehicle at our store, our company will reimburse their one-way personal airfare and overnight accommodation expenses, with the ultimate ownership belonging to our company.)
We will use a megohmmeter (insulation resistance tester) to measure the insulation resistance of the high-voltage bus. If the resistance value is below the national safety standard, it indicates a risk of leakage, and the vehicle will be deemed unqualified.
From a technical perspective, China's "National VI B (China VI-b)" is one of the strictest emission standards globally, with limits on carbon monoxide, nitrogen oxides, and particulate matter that are even stricter than some of Europe's Euro VI standards. However, the two are not legally recognized by each other, depending on your country's import regulations.
Do not use a high-pressure water gun directly! The high-pressure water can instantly damage the fragile aluminum fins of the condenser, leading to a permanent decrease in cooling efficiency. We can only use a low-pressure air gun or a soft brush for surface cleaning.
