The toxicological properties of the vehicle shall be repo
20、rted as in 4.5. 3.3 Quality The vehicle, as received by purchaser, shall be uniform in quality and condition, clean, and free from foreign materials and other contaminants detrimental to usage of the vehicle. 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for Inspection The vendor of the vehicle
