I'm a member of both and enjoy both sites very much. Mercedesshop is more tech oriented and the favorite cars here are older ones and Diesels. Benzsport is more for tuning a MB which MBenz already stated. I don't think that site is rice because pretty much everyone has tasteful modifications. I think it's important to encourage the growth of the MB tuning community. There are more and more companies that are offering products for MB's and there is more of a market for them now. I think it's great.
