When purchasing a car, you can determine whether it's a new car or a stock car by checking the vehicle nameplate, tire wear, and manufacturing date. The vehicle nameplate is usually located below the B-pillar on the passenger side, mainly including the manufacturer's brand, model, engine power, total weight, manufacturing number, manufacturing date, and manufacturer name. Check the manufacturing month and year. If the manufacturing date is within three months of the purchase date, it is not a stock car. If it exceeds three months, it can basically be considered a stock car. Generally, new car tires show little to no wear, and the tire hairs on the sidewalls are clearly visible. If you notice the absence of tire hairs, pay attention and then check the tire's manufacturing date. There is a string of numbers on the tire sidewall, with the latter group representing the manufacturing year and the former group representing the week, allowing you to calculate the tire's manufacturing date. Then, compare it with the vehicle's manufacturing date on the nameplate. If the dates are close, it proves it's not a stock car. If there's a significant time difference, you need to be cautious.

As an enthusiast who has been studying vehicle details, I pay special attention to body markings and component conditions when identifying stock cars. First, check the production date, which is usually marked on the nameplate near the driver's door frame or under the hood. If the date is more than six months old, it's likely a stock car. Feel the tires with your hands—those stored for a long time may have cracks or slight deformations. Also, test-start the engine, as the battery tends to degrade, leading to slow ignition. If the interior smells musty or dusty, it indicates prolonged storage. Stock cars carry high risks due to aged rubber and fluids, potentially requiring costly repairs after purchase. That's why I always bring a small flashlight to thoroughly inspect every car I consider buying.

As an average consumer who got a bad deal last time I bought a car, I've learned my lesson: The best way to identify stock vehicles is to start with practical checks. Ask the salesperson directly how long the car has been in stock—anything over a few months should raise red flags. Inspect the door hinges and seat bases; stock cars often show rust or uneven lubrication. Open the fuel cap and take a sniff—spoiled fuel has a distinct odor. Check the odometer reading; stock cars usually show very low mileage, but don't be fooled. During the test drive, listen for smooth engine noise—any roughness could mean dust buildup from prolonged storage. Always negotiate the price beforehand, as stock cars come with big discounts but also hidden risks.

For us young people buying cars, we aim for convenience and affordability. Identifying stock cars is quite simple: mainly look at the price and manufacturing date. If a dealership's advertisement offers steep discounts, it's likely a stock car. The manufacturing date can be found on the nameplate or in the manual—avoid anything over 3 months old. Quickly check the tire wear and battery condition, as prolonged storage can cause issues. It's advisable to bring a friend along for a quick inspection when choosing a new car to ensure safety.

I always choose cars carefully, and identifying stock vehicles requires a comprehensive inspection: start by checking the production date via the VIN code—if it's over six months old, be suspicious. Next, examine the engine oil color; if it's turned from golden to cloudy, that's a sign of being in stock. Test the battery voltage—if it's low, it indicates aging. Also, look for dust accumulation in the body gaps, and sluggish brake response during a test drive is another clue. Although stock vehicles are cheaper, long-term storage increases maintenance risks, so be sure to have a technician conduct a detailed evaluation before purchasing.
