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.
