You can only buy Smart from Mercedes-Benz dealers. Not all Mercedes-Benz dealers can sell Smart. I remember it seems that only Lixinghang dealers sell Smart. Taiyuan Star is owned by Lixingxing, so it should have Smart. Even if you don't have a good relationship with their sales manager, he will help you book a car from outside. Most Mercedes-Benz dealers in North China belong to Li Xingxing Group, so it is generally not difficult to transfer cars from outside.
