How do I flip a car upright properly?

In my opinion, BodyMovers are confusing. I'm trying to make a script that flips a car upright whenever you press V. However, it's not doing that, and making the car turn erratically instead. I'm using a BodyGyro to flip the car by the way. Here is my script:

local player = game.Players.LocalPlayer
local camera = workspace.CurrentCamera
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")
local UserInputService = game:GetService("UserInputService")
local inCar = false
local vehicle

local function onSit(Sitting, seat)
    if Sitting == true then
        if seat.Name == "DriveSeat" then
            inCar = true
            vehicle = seat.Parent.Parent
            camera.FieldOfView = 100
            repeat wait()
                camera.CameraType = Enum.CameraType.Attach
            until camera.CameraType == Enum.CameraType.Attach
        end
    else
        inCar = false
        camera.FieldOfView = 70
        repeat wait()
            camera.CameraType = Enum.CameraType.Custom
        until camera.CameraType == Enum.CameraType.Custom
    end
end

local function flipCar(car)
    if inCar then
        local yRot = car:FindFirstChild("Car Weld").DriveSeat.Orientation.Y
        local seat = car:FindFirstChild("Car Weld").DriveSeat

        seat:FindFirstChild("BodyGyro").CFrame = CFrame.fromOrientation(0, -1*yRot, 0)
    end
end

local function flip(Input)
    if Input.KeyCode == Enum.KeyCode.V then
        flipCar(vehicle)
    end
end

humanoid.Seated:Connect(onSit)
UserInputService.InputBegan:Connect(flip)

Any help would be appreciated.
