There are many auto repair shops in Shijiazhuang, but there are not many auto repair shops specializing in Mercedes-Benz and BMW, especially the larger ones. The only one that meets the requirements is Zhuang Xuchi's luxury car store chain, which is the largest store in Mercedes-Benz and BMW. The storefront area is nearly 5000 square meters, and No.36 Tianshan Street in High-tech Zone should be able to meet your requirements.
