I have a vehicle, (Which is a model) and I want to move the entire vehicle while a person is sitting in it, While keeping them in the seat.
What you want to do is in studio choose a part in model as primary part
Then use one of model api functions :MoveTo()
local myCar = game.Workspace.MyCar --just an example maCar:MoveTo(Vector3.new(0,0,0)) --moves to the center of the map --You can also use the cframe one maCar:SetPrimaryPartCFrame(CFrame.new(0,0,0))
Remember to 1.Set car model primary part.
