While seeing Chinese cars on display at the Detroit Auto Show has become somewhat common these past few years, there is one place they were hardly expected: Costco!

Yes, the big-box discount store Costco could be selling the Chinese-designed and Mexican-built vehicles says one auto exec. The CEO of GS Motors — Kathleen Ligocki — told the Hybrid Cars website that she thinks the US will follow in Mexico’s footsteps. GS Motors sold 4,000 China-made vehicles in Mexico last year at…Costco and Wal-Mart.

My first thought: If they are sold at Costco, will they come individually wrapped and in a pack of ten?

Auto critics have ridiculed the cars for both design and quality flaws. But hey, Japanese and Korean cars once received the same treatment. And I think it’s safe to say that Honda and Toyota got their footing.

Ligocki, who previously served as president of Ford of Mexico, said the next step is for Chinese-designed cars to go into production in Mexico in 2010. She expects them to hit the American market about five years later. Hybrid Cars reported that GS is building an assembly plant in Michoacan, Mexico, with the China-based FAW Group who has formed joint ventures with automobile giants such as Volkswagen, Toyota and Mazda.

GS Motors will launch the FAW brand in Mexico this year with the F1 Hatchback, an entry-level car sold for under $5,500. FAW, one of the largest Chinese automakers, is allied in China with Volkswagen.
