When a model gets cloned, i cant sit on the vehicleseat even tho its not disabled?

I made a car, that clones when u join. But when it clones, i cant sit in it. Why is that?

script:

local debounce = false
local uis = game:GetService("UserInputService")
local plr = game.Players.LocalPlayer
uis.InputBegan:Connect(function(k)
	if k.KeyCode == Enum.KeyCode.G then
       if not debounce then
	for i,v in pairs(game.Players.LocalPlayer.Character:GetChildren()) do
		if v:IsA("Model") then
		v:Destroy()
		end
	end
	wait(0.1)
		 local car = plr.SelectedCar.Value:Clone()
		car.Parent = game.Players.LocalPlayer.Character
		car.Name = plr.Name..("'s Car")
		car:SetPrimaryPartCFrame(plr.Character.Head.CFrame * CFrame.new(0,0,-10))
		car.Chassis.Base.Anchored = false
		car:MakeJoints()
		debounce = true
		wait(1)
		debounce = false
end
end
end)
