Russia, like China, is a growth country. As the market develops over time, Russia has the potential to be a market as large as the US. The US (as well as Japan and Western Europe) is a stagnant market. Sales of light-vehicles isn't going to change much; sure it goes up a few points and down a few points, but it's going to hover around 16.5 million units a year. Russia current builds one million vehicles a year, primarily for the Russian market (and those of other former Soviet countries).
There's little thought of bringing Russian-built Focuses (Focii?) to North America or Western Europe. But getting production in Russia is a big deal for the future growth of any major car company.
You folks do know that the Focus is more a German car than an American car, right? The argument that German cars were better than the Focus seemed like a perplexing debate.
