Hello Jim's Sierra 2005 Without double Gear transmission Engine gear machine, fully tuned, most parts are GM, replaced radiator with original agency parts, Nissan thermostat, and the engine has no overheating issues Equipped with electronic supercharger + programmed (Bob Corn) Engine mileage 400, replaced odometer Looking for agency price, the engine has been repainted cosmetically, most trims are clean, needs minor整理 regarding seats, upholstery has been slightly lifted, overall in agency condition (No one should undervalue its price, may God not disgrace you)
