To estimate the price of the 2012 Hyundai Elantra I4 1.6L GL (Mid), I first considered the selling prices of similar cars. A 2011 Elantra 1.6L Smart (Base) with similar mileage and condition sold for 21000 SAR recently. A 2013 Elantra 1.6L GLS (Top) with slightly higher mileage sold for 29000 SAR, but it is a higher trim. A 2012 Elantra 1.8L Smart (Base) with higher mileage sold for 20000 SAR. The 2012 Elantra 1.8L GL (Mid) was listed for 31000 SAR but was not sold, indicating a likely lower market value. Considering the 2012 model year and the mid-trim level, the estimated price should be slightly higher than the 2012 1.8L Smart (Base) but lower than the 2013 1.6L GLS (Top).
