I know you can rotate a part but can you rotate an entire model?

I'm making a city simulator game but the car I'm scripting using the MoveTo method theres a way it has to turn how to make it "Turn" Using rotate? or is it not possible?:

There is currently no built-in method of rotating models, but studying scripts such as CmdUtil that allow you to rotate models from Studio might be a step in the right direction.

Hey, sry about not Commenting, I cant Comment for some Stupid Reason -_- This:

w = script.Parent.Parent.Parent.Doors.Door1 
d = script.Parent.Parent.Parent.Doors.Door2 

for r = 1,30 do 
wait() 
for r,p in pairs(w:GetChildren()) do if (p.className == "Part" or "Wedge" or "Truss" or "Seat") then p.CFrame = p.CFrame - Vector3.new(0,0,-3) end end 
for r,p in pairs(d:GetChildren()) do if (p.className == "Part" or "Wedge" or "Truss" or "Seat") then p.CFrame = p.CFrame - Vector3.new(0,0,3) end end 
end 

Should be:

w = script.Parent.Parent.Parent.Doors.Door1 
d = script.Parent.Parent.Parent.Doors.Door2 

for r = 1,30 do 
wait() 
for r,p in pairs(w:GetChildren()) do if (p.className == "Part" or className == "Wedge" or className == "Truss" or className == "Seat") then p.CFrame = p.CFrame - Vector3.new(0,0,-3) end end 
for r,p in pairs(d:GetChildren()) do if (p.className == "Part" or className == "Wedge" or className == "Truss" or className == "Seat") then p.CFrame = p.CFrame - Vector3.new(0,0,3) end end 
end 

every time className == has to be repeated (from my experience, and again, sry for not Commenting, my Comments are Disabled for some Stupid Reason...

You have to define the models and then get the children then Cframe the children like so:

w = script.Parent.Parent.Parent.Doors.Door1 
d = script.Parent.Parent.Parent.Doors.Door2 

for r = 1,30 do 
wait() 
for r,p in pairs(w:GetChildren()) do if (p.className == "Part" or "Wedge" or "Truss" or "Seat") then p.CFrame = p.CFrame - Vector3.new(0,0,-3) end end 
for r,p in pairs(d:GetChildren()) do if (p.className == "Part" or "Wedge" or "Truss" or "Seat") then p.CFrame = p.CFrame - Vector3.new(0,0,3) end end 
end
