How can I make a dialog shop sell cars that don't fall apart?

In the roblox tutorials, you have the option to make a dialog shop. The only thing is, In the tutorial they only show you how to add items your character uses to your backpack; so like a sword. I however want to make it sell cars.

Tutorial script.

local dialog = script.Parent
dialog.DialogChoiceSelected:connect(function(player, choice)
    -- Check the player has a stats object
    local stats = player:FindFirstChild('leaderstats')
    if not stats then return end
 
    -- And that the stats object contains a gold member
    local gold = stats:FindFirstChild('Gold')
    if not gold then return end
 
    if choice == script.Parent.DialogChoice.ChoiceA then
        if gold.Value >= 5 then -- 5 is the amount of gold you need to purchase this weapon
            game.ReplicatedStorage.Weapon1:Clone().Parent = player.Backpack
            gold.Value = gold.Value - 5 -- subtract the amount of gold you need to purchase
        end
    elseif choice == dialog.DialogChoice.ChoiceB then
        if gold.Value >= 10 then
            game.ReplicatedStorage.Weapon2:Clone().Parent = player.Backpack
            gold.Value = gold.Value - 10
        end
    elseif choice == dialog.DialogChoice.ChoiceC then
        if gold.Value >= 15 then
            game.ReplicatedStorage.Weapon3:Clone().Parent = player.Backpack
            gold.Value = gold.Value - 15
        end
    end
end)

I attempted to modify this...

local dialog = script.Parent
dialog.DialogChoiceSelected:connect(function(player, choice)
    -- Check the player has a stats object
    local stats = player:FindFirstChild('leaderstats')
    if not stats then return end -- If not end script
 
    -- And that the stats object contains a money member
    local money = stats:FindFirstChild('Money')
    if not money then return end
 
    if choice == script.Parent.DialogChoice.ChoiceA then
        if money.Value >= 5 then -- 5 is the amount of money you need to purchase this car
            game.ReplicatedStorage.Sportscarblue:Clone().Parent = game.Workspace
            money.Value = money.Value - 5 -- subtract the amount of money you need to purchase
        end
    end
end)

Since I'm still grasping the understand of Cframes and teleportation... I put the car in replicated storage. I then moved the car that was in storage to be positioned over a pad that would be used for a car delivery point. Everything went fine, put when the car is actually spawned, It falls apart into all the parts used to build the model.

So, how can I get a dialog shop to sell a model while keeping the models integrity upon cloning/teleportation?

I think you need to weld all the parts of the car together. Try getting a Easy-Weld Plugin. highlight all the parts and weld them together. Welding holds everything together.

I'd also recommend trying to Anchor and Unanchor the car model.
