How many months is considered as stock car for joint-venture vehicles?

[Megan]

Joint-venture vehicles exceeding three months are considered as stock cars. Potential issues with stock cars include: 1. Moisture damage and aging: After leaving the factory, various fluids, electronic components, batteries, rubber seals, and tires may suffer from moisture damage and aging due to prolonged storage without periodic inspection and maintenance; 2. Weather exposure: Only a very few dealers implement periodic inspection and maintenance measures, which actually don't cost much but consume manpower and time. Some 4S stores even park new cars in open-air garages, exposing them directly to scorching sun, wind, and rain; 3. Oil and power shortage: For stock cars stored for too long without proper warehouse management, the aging degree of electronic components and rubber products is basically undetectable without professional testing equipment. Many vehicles stored for too long also experience oil and power shortage issues.
