Hyundai Sonata 2018 Automatic Gasoline mileage: 300 KM or more Sonata 2018, mileage just entered 300. Chassis, gearbox, airbags are factory condition. The engine had its head resurfaced a year ago and its condition is very, very good and it doesn't complain about anything, thank God. The body is full factory except for the right fender, and the dent is present before painting. I'm posting it for you.
