How Can I Make A Car Explode When Something Breaks In It?

I'm not really a scripter, however I've extracted this code from an aircraft, this will explode upon impact, which isn't what you're looking for however it's a start.

repeat wait() until script.Parent.Welded.Value --This line makes the plane invulnerable to weapons when it is still welding
wait(0.1)
local Plane = script.Parent --Lines 3 - 10 set variables
local AutoCrash = Plane.AutoCrash
local Ejected = Plane.Ejected
local Engine = Plane.MainParts.Engine
local CanCrash = Plane.Customize.CanCrash
local Force = CanCrash.Force
local Crashed = Plane.Crashed
local Parts = {}
--------------------------------------------------------------------------
function Explode() --This function makes the plane explode
    if Crashed.Value == false then
        Crashed.Value = true
        Plane:BreakJoints()
        local Explosion = Instance.new("Explosion")
        Explosion.Parent = game.Workspace
        Explosion.Position = Engine.Position
        Explosion.BlastRadius = Plane:GetModelSize().magnitude --This makes the BlastRadius the size of the plane
        Explosion.BlastPressure = 200000
        if Engine:findFirstChild("Thrust") then Engine.Thrust:remove() end
        if Engine:findFirstChild("Direction") then Engine.Direction:remove() end
        coroutine.resume(coroutine.create(function()
            wait(5)
            Plane:Destroy()
        end))
    end
end

function GetPlaneParts(Model) --This function gets all the parts on the plane
    for _,v in pairs(Model:GetChildren()) do
        if (v:IsA("BasePart")) then
            table.insert(Parts,v) --This inserts all the parts into the "Parts" table
        end
        GetPlaneParts(v)
    end
end

function onAutoCrash() --This function is activated when the AutoCrash value becomes true
    if AutoCrash.Value == true then
        Plane:BreakJoints()
        Explode()
        Engine.Thrust:remove()
        Engine.Direction:remove()
    end
end

function DetectExplosions(Object) --This is a function that I created which detects explosions in the workspace
    if Object.ClassName == "Explosion" then --If the object detected was an explosion...
        if Object.BlastPressure > 0 then
            Object.Hit:connect(function(HitPart,Distance)
                if HitPart == Engine then
                    if Crashed.Value == false then
                        Explode()
                    end
                end
            end)
        end
    end
end

GetPlaneParts(Plane) --This activates the "GetPlaneParts" function
for _,v in pairs(Parts) do --This gets all the parts in the "Parts" table
    v.Touched:connect(function(Object) --This is activated if any of the bricks are touched
        if (not Ejected.Value) then
            if CanCrash.Value == true then
                if Crashed.Value == false then
                    if (not Object:IsDescendantOf(Plane)) then
                        if Object.CanCollide == true
                        and Object.Transparency ~= 1 then --This prevents your from crashing because your flares hit you
                            if (Object:findFirstChild("PlaneTag") and Object.PlaneTag.Value ~= Plane)
                            or (not Object:findFirstChild("PlaneTag")) then
                                if ((Engine.Velocity.magnitude) >= Force.Value) then --If that part is going faster than the Force speed...
                                    local Player = game.Players:GetPlayerFromCharacter(Plane.Parent)
                                    local PlaneTool = Player.Backpack:findFirstChild("Plane")
                                    if PlaneTool then
                                        PlaneTool.Deselect0.Value = true
                                    end
                                    wait(0.01)
                                    Explode()
                                end
                            end

game.Workspace.DescendantAdded:connect(DetectExplosions) --The detect explosions is a childadded function
AutoCrash.Changed:connect(onAutoCrash) --Pretty self explanatory. When the AutoCrash value is changed, the "onAutoCrash" function is activated
