LTZ 2014 Automatic Gasoline mileage: 300 KM or more Peace, mercy, and blessings of God be upon you. I have an Impala model 2014 LTZ. Full option. Mileage 390. The car is very sound, gearbox and engine are factory condition, never opened. The body has been repainted for cosmetic purposes, except for the roof. The highest offer is 26,000, and the sale is near, God willing.
