To estimate the price of the 2020 Range Rover Vogue SV Autobiography V8 Supercharged (Top) with 48000 km mileage and Non-GCC specs, I considered the listed prices of similar cars. The first car, with identical specs and mileage, is listed for AED 389000. The second car, with higher mileage (66900 km) and American specs, is listed for AED 195000. The third car, with slightly higher mileage (67082 km) and Non-GCC specs, is listed for AED 359000. Given the condition and mileage of the target car, I weighted the first and third listings more heavily. The average of these two prices is (389000 + 359000) / 2 = 374000 AED. Considering the target car's condition and market trends, I adjusted slightly downward.
