It's not known if any of them have been bought. I think that store is located in some kind of bonded zone! But that's not a 4S store yet, it's a 3S store.
Now there are several, located in Beijing, Shanghai, Hangzhou, Quanzhou, Guangzhou, Shenzhen, Chengdu.
I don't know if the one in Kunming is a 4S store, but at least it's a 3S, and an Evantado was delivered some time ago. It's said that Lamborghini will set up 20 points in China in the next two years, and Changsha is among them, and it's said to be officially opened later this year (one said December this year)... Quite a few provincial capitals are among them...
