If your business plan was a car, what type would it be?

I think of cars in terms of how useful they are in my life, and how easy or hard they make it. And that can be a useful lens to inspect your company strategy as well. Is your business plan working well? Or is it due for a service and MOT? Or even an upgrade to a better model? Cars don't last forever, and neither does your first shot at a business plan. Which of these types of car does your current business planning most resemble?
