Dealership invoice refers to the purchase invoice from a 4S store, while auto trade invoice refers to the purchase invoice from an auto trade company. The differences between the two lie in the after-sales service and price of the vehicle. Generally, buying a car from a 4S store is more expensive than from an auto trade company. This is because auto trade companies source vehicles from 4S stores with the lowest prices nationwide, whereas 4S stores source directly from manufacturers. Additionally, the operational costs of 4S stores are higher than those of auto trade companies, resulting in different prices on the invoices. Using an auto trade invoice might affect the vehicle's future after-sales service. Some vehicles purchased from auto trade companies may only receive after-sales service at local 4S stores, which may not be recognized by 4S stores in other regions. However, with a 4S store invoice, after-sales service can be obtained at any 4S store nationwide. How to distinguish between a genuine auto trade invoice and a 4S store invoice: Check the watermark: Genuine invoices are printed on special anti-counterfeiting paper with black and white watermarks, and the watermark pattern has a noticeable texture when touched. Fake watermarks have a weaker texture and appear blurry. Prize area difference: The covering layer in the prize area of a genuine invoice is made of laser gold-stamped film, presenting a matte finish, while most fake invoices have inferior covering layer technology in the prize area. Color difference: Genuine invoices have a deeper color, appearing pinkish, while fake invoices have a much lighter color, looking somewhat pale.

As a seasoned driver with over a decade of experience, I've gone through several car purchases, and the most noticeable difference is between dealership invoices and auto trade invoices. Dealership invoices are typically issued by 4S shops, with the advantage of reliable car sources and direct warranty claims at the dealership, eliminating extra worries. I once bought a car from a well-known brand's 4S shop, with complete invoices, where minor issues during the warranty period were fixed for free, and the service was considerate. In contrast, auto trade invoices are often issued by auto trading companies, and while the prices are indeed cheaper, I once bought a cheap parallel import car to save money. The invoice looked the same, but the warranty was basically a gamble—when the engine had problems, I had to pay for repairs myself, and transferring ownership might raise questions about the car's unclear origin. I recommend that new car buyers prioritize dealership invoices for peace of mind, not just focusing on the price difference of a few thousand dollars, as long-term maintenance costs could be higher.

I've worked in an auto repair shop for several years and encountered many owners bringing in used cars with dealership invoices or auto trade invoices for repairs. Cars with dealership invoices are typically sold by 4S shops, with complete invoice records and traceable maintenance data. The manufacturer directly handles the warranty, and replacing parts isn't a hassle. However, cars with auto trade invoices have invoices issued by trading companies. These vehicles might be parallel imports or come from second-hand dealers, and their maintenance manuals aren't standardized. I once repaired one with a circuit malfunction that took ages to diagnose because the wiring had been modified, and the invoice was no help at all. When buying a car, be extra cautious—ask where the car's systems were installed. Don't just place an order because the invoice is cheap, or you might end up wasting money on repairs. The warranty gap is key; cars from trade channels tend to have higher failure rates.

I've always wanted to save some money to buy a new car, so I compared the differences between dealership invoices and auto trade invoices. Dealership invoices are official invoices from authorized 4S stores, where the car is more expensive by ten or twenty thousand, but it comes with original factory warranty and hassle-free insurance. Auto trade invoices are much cheaper, issued by trading companies, suitable for tight budgets; but once I almost bought one, and a friend reminded me that the after-sales service is poor—the invoice looks legal, but the car might have been modified, and if problems arise, there's no warranty. So I gave up on saving that money to avoid the hassle of repairs later. When buying a used car, it's even more important to check the source of the invoice—don't court trouble by being greedy for a cheap deal.

When helping a friend choose a car, I must pay close attention to the invoice type. A dealer invoice is the sales document from a 4S store, offering comprehensive warranty and service guarantees. On the other hand, a trade invoice comes from an auto trading company—it may be cheaper but carries higher risks. Even if the invoice details look the same, the car might not come through official channels, leading to reduced or invalid warranties. I recommend opting for a dealer invoice, as it ensures higher resale value and smoother claims processing in case of accidents. Ordinary consumers often overlook this—don’t jump into a pitfall just to save a little money.
