To estimate the price of the 2015 Bentley Flying Spur V8 4.0L Twin Turbo V8 (Base), I first considered the selling price of a 2013 Bentley Flying Spur W12 6.0L Twin Turbocharged with 96000 km mileage, which sold for SAR 109000 on 2024-01-09. Given that the car in question is a 2015 model with a smaller engine (V8 vs. W12) and lower mileage (59000 km), it should be priced higher. Next, I looked at the listed prices: a 2016 Bentley Flying Spur W12 6.0L Twin Turbocharged with 59000 km is listed for SAR 256000, a 2013 model with 56000 km is listed for SAR 165000, and a 2014 model with 79000 km is listed for SAR 240000. These listed prices are generally higher than actual selling prices. Considering the depreciation and the fact that the car in question is a base variant, I adjusted the price downwards from the listed prices. Factoring in the lower mileage and the newer model year, I estimated the market price accordingly.
