By 1986 Austin-Rover, or whatever it was calling itself that week, were effectively finished. They were propped up by public finances and were losing money on a day-by-day basis.
Ford were wise to not have got involved and BMW were very foolish to have allowed themselves to buy the shambles, which was after B.Ae. had a go at making it work, but at least BMW got the 'Mini brand and name which has seen them with some sort of advantage.
Austin-Rover never seemed to understand marketing, whereas Ford always have. Ford don't compete with themselves and they produce cars which people want at prices they are prepared to pay. The later Rover 200, 400 & 600 series were excellent cars, but the marketing strategy was badly flawed. I have had a 214Si, two Rover 600 models and a 420i. All very good and nice to drive, but the target markets were badly defined. Then there was the poor way in which ARG dealt with their supplier chain, failed to pay invoices within a reasonable time and made poor decisions. The trades unions didn't help either.
Why would Ford have made any sort of an offer without full disclosure by ARG. It's called 'due diligence' and as ARG was largely gov't funded it is natural that the gov't would insist on full disclosure being available. If Ford had made any sort of offer without full disclosure by ARG then the Ford executives would have been guilty of negligence. I have been involved in acquisitions of companies and full disclosure is always required.
It is the press which doesn't seem to understand how the sale of businesses works and use 'sensationalist' headlines in order to sell newspapers.
