New cars that have been in stock for 3 months are considered stock cars. Stock Cars: In fact, there is no clear legal definition for so-called "stock cars," but in the automotive sales industry, there is indeed a term called "stock cars," which generally refers to cars that have been in stock for more than three months without being sold. Commercial Vehicles: As a commodity, cars are large in size, expensive, and have high storage costs, while also occupying a significant amount of dealers' capital. Therefore, dealers generally do not allow commercial vehicles to remain in stock for extended periods. However, there are indeed many cars in the market that have been in stock for more than three months. As for quality issues, they still need to be judged based on the actual vehicle.

When I bought my last car, I did a lot of research, and the issue of stock vehicles is quite interesting. Generally, a new car is considered a stock vehicle if it has been more than 6 months since its production date. However, in practice, multiple factors need to be considered. For example, luxury brands tend to have longer inventory cycles than mainstream brands, and SUVs may stay in inventory longer than sedans. I also noticed that seasons play a role—cars produced in spring are more likely to become stock vehicles if they remain unsold by year-end. When purchasing, pay special attention to checking whether the brake discs are rusty or if the tires are deformed, as these details can reveal the actual storage duration. Some dealers might move stock vehicles around to disguise them as new cars, but the most accurate method is to check the production date on the vehicle identification number (VIN) plate. If you encounter a stock vehicle, don’t panic—you can definitely negotiate a 20% lower price, but make sure the dealer replaces fluids like engine oil as a condition.

Regarding how long a new car is considered a stock car, I see many friends are quite confused. Actually, there are no particularly rigid rules, but the generally accepted standard in the automotive circle is that it's been over 6 months since leaving the factory. However, the key is to look at the storage environment. If it's stored in an underground temperature-controlled garage, a car sitting for 8 months might be in better condition than one parked outdoors for 3 months. Personally, I pay special attention to the tires, as cars parked for long periods are prone to developing flat spots on the tires. Engine oil is also a critical factor for judgment; oil may oxidize if the car sits for more than half a year. Nowadays, savvy buyers check the code label on the car window—the first two digits of that number represent the production month. If you discover it's a stock car, don't rush to reject it outright. You can request a free full fluid change, which significantly reduces the risks. After all, stock cars offer obvious price advantages, and it's common to save seven or eight thousand yuan.

Identifying inventory cars is actually quite straightforward. I usually use three months as the threshold: within three months is considered a new car, three to six months is the borderline period, and anything over six months is definitely an inventory car. I remember last time when I accompanied a friend to pick up a car, we saw leaves and dust accumulated under the windshield in the parking lot—clearly, it had been sitting there for a long time. The key is to check the production date on the nameplate and compare it with the pickup date to calculate the time difference. Some imported cars take two to three months just for shipping, so anything within six months is generally acceptable. If you do encounter an inventory car, don’t worry—just ask the 4S dealership to replace the battery and engine oil, and they usually agree. After all, for cars that have been parked for a long time, rubber components age faster than with normal use.
