Where does someone like Rover fit in to your matrix? If I can respectfully recommend. If you can go have a read of "We sell our time no more" by Paul Stewart.
Tory governance and fiscal policies had all the responsibility for Leyland, Hillman and more importantly Rover.
I have to admit it's not that deeply researched. That book sounds interesting.
For Rover in particular, https://en.wikipedia.org/wiki/Phoenix_Venture_Holdings stands out. Similar to Maplin and Toys R Us, an example of the owner-management taking a large amount of cash out of a business that was declining.
