To estimate the price of the 2012 Audi A6 TFSI I4 2.0L Turbocharged 45 TFSI (Top) in bad condition with 277000 km mileage, I considered several data points. First, I looked at the selling prices of similar cars: a 2012 Audi A6 with 310000 km sold for 32000 SAR, a 2013 Audi A6 with 259000 km sold for 27099 SAR, a 2013 Audi A6 with 128000 km sold for 38500 SAR, and a 2014 Audi A6 with 219000 km sold for 43500 SAR. Given the bad condition of the target car, I adjusted the price downwards. Next, I reviewed listed prices: a 2012 Audi A6 with 266500 km listed for 36500 SAR, a 2014 Audi A6 with 290500 km listed for 30000 SAR, and a 2013 Audi A6 with 259000 km listed for 32500 SAR. Considering the bad condition and higher mileage of the target car, I further adjusted the price downwards. Finally, I factored in the depreciation and the condition of the car to arrive at a fair market price estimate.
