This kind of thing actually happens quite frequently in repair shops. Many car owners are not sensitive to their vehicles and lack deep knowledge. During maintenance, they change parts without the owner realizing. What they replace are not original factory parts, but rather substandard aftermarket parts. Put simply, they're defective products. An original factory part costs around five or six hundred yuan, while the substandard parts they use cost roughly ten to twenty yuan. With this swap, a profit margin emerges. And the more expensive the car, the higher the value of its parts. Coming across a luxury car in the shop for repairs, the temptation is just too great. With just a bit of tweaking, they could make a profit of tens of thousands! Much more than they could make by honestly earning a salary.
