Restructuring General Motors is crucial for the survival of the worlds second largest carmaker. So it should be done thoroughly and not in a half-hearted manner.
And that means Vauxhall will have to go.
One area that needs urgent attention is GMs large number of brands.
The success of Honda, Toyota and Nissan is based on their clear presence in all markets with one single mainstream brand, each backed up by an upmarket nameplate: Acura, Lexus and Infiniti.
Mercedes-Benz (with Smart), BMW (with Mini) and Volkswagen (with Audi) have the same strategy.
Even Ford Motor, though it is also suffering today, is known as a global brand, backed up by the luxury Lincoln label in the US. It can do without Mercury and Volvo.
So GMs restructuring scenario must be clear: it needs just one mainstream value brand, one slightly more upmarket nameplate, and a luxury marque. All three should have a global presence. They should be called Chevrolet, Opel and Cadillac.
Abandoning US brands Pontiac, Saturn and Hummer -- and Saab in Europe -- are the obvious choices and they have already been made. But GM should now also review its policy of having regional brands.
It should drop Buick, which is only sold in America and China. It should consider dropping Holden in Australia. And forget about Vauxhall, which is nothing more than another nameplate for German-made Opels.
Vauxhall admittedly sells more cars in the UK than Opel does in Germany. But that does not justify keeping the nameplate for one single national market. It doesnt make sense to restrict the generally successful Opel brand to sell its cars only in continental Europe. It costs extra money to market Vauxhall, it requires different local dealer standards and confuses the market.
Instead, GM should make Opel, which offers the highest quality of all GM products, a world brand. It should also be sold in the UK and Australia.
Opel has the potential to grow globally as GMs main sub-premium brand And it can do so bearing a made in Germany badge with pride and justification.
