To estimate the price of the 2016 Audi A5 35 TFSI S-Line I4 1.8L Turbocharged, I considered the listed prices of similar cars. The closest match is a 2016 Audi A5 35 TFSI S-Line I4 1.8L Turbocharged with 185,000 km listed for SAR 59,500. Given the target car has significantly lower mileage (45,000 km), it should be valued higher. A 2018 Audi A5 40 TFSI Quattro S-Line with 185,000 km is listed for SAR 90,000, and a 2018 Audi A5 40 TFSI with 110,200 km is listed for SAR 78,000. Considering the year difference and mileage, the target car should be priced lower than these 2018 models. A 2015 Audi A5 35 TFSI with 210,000 km is listed for SAR 39,000, which is much older and has higher mileage. Factoring in the lower mileage and average condition of the target car, I estimate its market price accordingly.
