Mazda Mazda 6 2016 Used Automatic Gasoline mileage: 400 KM or more For sale, Mazda 6, model 2016 Mileage: 400 thousand and some change Most parts have been changed and are new, invoices are available, tires have been changed and are clean. The gearbox is original and sound. There are some minor scratches on the exterior body. The engine is working, but sometimes white smoke comes out of the exhaust, and sometimes no smoke comes out. I am clearing my conscience. The price of the engine if you want to change it is 3500. A 2019 engine from a junkyard with less than 100,000 miles is available in a shop in Quways for a two-month warranty if you wish to change it. However, the car currently has no engine noise and is working, but the only issue is the smoke.
