The car to be estimated is a 2020 Audi Q8 55 TFSI Quattro S-Line V6 3.0L Turbocharged with 66000 km mileage. The closest data point is an offer accepted for a similar 2020 Audi Q8 55 TFSI S-Line (Top+) with 94000 km mileage at SAR 208000 on 2024-06-28. Given the lower mileage of the car to be estimated, it should be valued higher. A listed price for a similar car with 94000 km is SAR 211500, which supports the accepted offer price. Considering the lower mileage and good condition, a reasonable estimate would be slightly higher than the accepted offer but not as high as the listed price, accounting for negotiation and market conditions.
