I think you will see Land Rover return to the distribution strategy they used a decade ago: small, specialized dealerships spread apart from one another geographically. I know that in my area, there are 6 Land Rover dealerships within an hour drive. 10 years ago, there was 1. I know from personal experience that sales at each of the dealerships are hurting; but are total sales in the region? No. Land Rover, until the recent economic downturn, has posted record sales numbers. They must be doing something right, in the eyes of consumers.
A consolodation of retail centers will alleviate many of the problems the brand faces today. So many dealers in such a small geographic area proliferates pricing wars, cannibalistic competition, and unhealthy rivalries. When I worked in the sales department at a dealership, I grew to hate the sales departments at the other regional dealers. They hated us in return.
Years ago, Land Rover "Centres" were destinations. People would travel from far and wide to come see the vehicles, the dealer, and the "experience". This quality has been lost with the current marketing strategy.
I think that the headline about the Defender being built on an LR3 platform does not signify a total departure from the company's roots, but rather a specialization and "honing" of different vehicles for different international markets. We have seen this from Toyota consistently; the FJ Cruiser and Tacoma are built for the North American market on a modified 4runner platform. Land Cruisers and Hiluxes elsewhere retain the brand's utilitarian integrity.
In my opinion, what you will see is a limited production (comparatively) rendition of the "Defender" marketed in North America and built on the LR3 platform. As pointed out earlier in the thread, the ROW Defender is still available globally and will remain so. It would not surprise me to see production of the ROW Defender shift to India to save costs.
In the United States, Land Rover will become a boutique brand similar to Porsche or, on a more expensive scale, Bentley. You will see small destination dealerships co-marketed with Jaguar (who is also trying to move further upmarket).
Land Rover ceases to exist as a utilitarian brand in the United States. The next 10 years will show the company becoming, to SUVs, what Bentley is to cars. Small production, extremely high quality, low volume, specialized SUVs. The ROW Defender will never be sold here, with us instead receiving a very high-market FJ Cruiser type vehicle wearing the Defender nametag.
