BMW does not own "Minor", it owns "Mini Minor". Maybe MGR could coax Triumph back from BMW.
I don't think the R25 platform has much life in it, it is basically twenty years old. There is no niche for the Morris Minor to be reborn as a saloon. The Volkswagen Beetle can bear testament to that. The Traveller is an icon, perhaps more so than the saloon.
BMW have used the same styling lines on the 5-series for decades and it was updated and interpreted for each new generation (the new one excluded). BMW employed this approach when designing the Range Rover, MINI, and Rolls Royce Phantom, all of which are highly successful designs with excellent detailing.
This is the way I think the Morris Minor Traveller could be designed. I also think there is a huge market for midi-MPVs and full-MPVs, and those which are seen as "cool" are the most in demand. This is why cars such as the Volvo XC90, Mercedes ML and Discovery are so popular. They can seat 7, but they are "cool". I, for one, can forsee the woodie Travellers being a huge hit. Proper packaging would avoid an MPV look, perhaps like the Peugeot 306 SW and Mercedes GST. It could look cutting edge like the Rolls Royce Phantom and Range Rover, yet retain the silhouette and styling lines of its predecessors. The rear doors would be concealed easily (The original had only two passenger doors). I think MGR would have a hit on their hands if they built this.
Also: In Ireland where I live, there are no Austins on the roads anymore: no Maestros, no Metros, no Montegos; I have never heard of the Morris Marina, nor has anybody else outside UK, more important export markets. Even with England, I doubt anybody under 35 knows what a Marina is.
All over Europe, the Mini is thought of as an "Austin", the marque is synomymus with the Mini despite the fact that it hasn't been badged as such since 1969. More interestingly, what you know as the "London" Taxi, is known all over Europe as the "Austin" Taxi
- I think this brand recognition could be built on, especially for supermini markets. It has a very English pedigree, and brings to mind such automotive icons.
