Perhaps, but it does not change the reason why Rover failed, which would have happened whether they'd had the money straight or not...
Don't take this the wrong way, I have no love for the phoenix five, but in no way did they destroy an otherwise solvent and good business, Rover had not been a strong business for a very long time.
I don't dispute that Rover wasn't a healthy company, however I don't think it was terminal at the point when BMW sold it to PVH. I don't think BMW did either or they wouldn't have lent PVH nearly half a billion pounds, which presumably they lost when Rover went under. Be interesting to know what BMW management think about all this.
The thing is, bad businesses can be turned around, but only if the people running these business have the will (amongst plenty of other things) to do so. This case here seems to be that PVH viewed Rover as an ageing cash cow, desperate to suck the last few remaining drops of milk before she falls over and dies.
