To estimate the price of the 2017 Jaguar XF R Sport I4 2.0L Turbocharged HSE (250 PS) with 134000 km mileage, I first looked at the selling prices of similar cars. The 2016 Jaguar XF I4 2.0L Turbocharged SE (250 PS) with 176500 km sold for 28500 SAR and another 2016 Jaguar XF I4 2.0L SE (250 PS) with 162000 km sold for 48000 SAR. Given the average condition and similar specs, these prices provide a baseline. Next, I considered the listed prices of similar cars. The closest match, a 2017 Jaguar XF R Sport I4 2.0L Turbocharged HSE (250 PS) with the same mileage, was listed for 62500 SAR. However, listed prices are generally higher than selling prices. Other listed prices for similar models ranged from 30000 SAR to 101000 SAR, but these had different specs and conditions. Considering the selling prices and the listed price of the exact match, I adjusted for the higher trim and closer year model, arriving at a reasonable market price estimate.
