Volkswagen is trolling the aisles of the global auto manufacturer market and looking for a new company to add to its cart. This week Malaysia's former prime minister confirmed the German automaker is in discussions with Proton to possibly buy a controlling stake or the entire state-run automaker outright. Proton's protected in its home country by a 300-percent tariff on imported vehicles, but the closed market will be opened to foreign competition in 2008. Proton, which also owns Lotus, would like to see a possible buyer commit to continuing to build Proton vehicles rather than just taking over the company's production capacity in Malaysia to build its own vehicles. VW has already announced it will be begin assembling the Passat and Fox in Malaysia with Proton.
