To estimate the price of the 2012 Hyundai Veloster I4 1.6L Turbocharged T-GDI (Top) with 183000 km mileage, I considered the listed prices of similar cars. The closest match is a 2012 model with the same variant and mileage listed for SAR 27500. Other relevant listings include a 2014 model with 176000 km for SAR 32000, a 2013 model with 170000 km for SAR 30000, and another 2013 model with 158000 km for SAR 29000. The 2013 model with 130044 km listed for SAR 21500 and the 2014 model with 252000 km listed for SAR 23000 were also considered. The average of these prices, adjusted for the condition and mileage of the target car, leads to a reasonable estimate.
