RS Q8屬於養車成本偏高嘅高性能SUV，定期保養只係其中一部分，性能胎、煞車零件、油液同其他損耗件先係較容易令賬單上升嘅項目。原廠人工同RS專用零件通常亦會比普通Q8貴，遇上一次過換多條胎或大型煞車零件，支出會明顯增加。買二手車前最好查清楚保養紀錄、輪胎剩餘壽命同煞車狀態，再向奧迪原廠或熟悉RS車系嘅專門車房索取逐項報價；香港實際價錢以最新報價為準。
The Audi RS Q8 sits at the costly end of Audi ownership. Routine servicing is only part of the bill: high-performance tyres, brake components, fluids and wear items can add up quickly, while dealer labour and genuine RS parts are usually priced above those for a standard Q8. Costs may rise sharply when several tyres or major brake parts need replacement together. Before buying a used one, check the service history, remaining tyre tread and brake condition, then ask an Audi dealer or specialist for an itemised quote. Exact Hong Kong prices should be confirmed with the workshop.
