The car to be estimated is a 2022 Porsche Cayenne V8 3.0L Coupe with 100,000 km mileage. There are no direct selling prices available, so I focused on listed prices of similar cars. The closest match is the 2022 Porsche Cayenne Turbocharged V6 3.0L with 39,000 km listed for AED 310,000. Considering the higher mileage of the target car, I expect a significant depreciation. Another relevant listing is the 2022 Porsche Cayenne 3.0L V6 with 23,000 km listed for AED 308,000. Given the target car's higher mileage and the fact that it is a V8, I estimate a lower price. The 2022 Porsche Cayenne 4.0L Turbo with 60,487 km is listed for AED 529,000, but this is a higher trim. Considering these factors, I estimate the market price for the target car to be significantly lower due to its mileage and condition.
