How to remove car after 20 seconds?

I have tried a script, and searched the web. and I found one which almost works. Only the wheels are left. It has the and wheels in a different model, within the entire carmodel. The script is inside of the Vehicle seat inside of the body.

local seat = script.Parent
local vehicle = seat.Parent

while true do
    wait(10)
    if not seat.Occupant then
        vehicle:Destroy()
    end
end

is what I have tried, can someone please explain, or fix the issue.

Thanks

Put this script In the car model `` local car = script.parent

wait (20) car:Destroy``

I figured it out, I had 1 parent too little, so it didn't remove the entire model, thanks for the help :)

script.Parent.ChildRemoved:connect(function()
		wait(10) --How long it has to wait before removing
		script.Parent.Parent.Parent:remove()--It is a model inside a model inside a model, so 3 parent
	end)

Here is a simple fix! I think you messed up on line 6. A lot of people like to do if statements when values are true and false like "if not true then" but I like to do it like "if value ~= true then"

local vehicle = script.Parent
local seat = script.Parent.Seat

while true do
	wait(10)
	if seat.Occupant == nil then
		vehicle:Destroy()
	end
end

This is a server script inside of a model.

Enjoy!
