Are all Wimmer representations recommended?

Hello to the TT forum… with my s2 coupé I have the one or other problem and wanted to have it checked out so easily. I already heard a lot of good about wimmer tuning (both in things tuning, as well as in things inspection) and especially here in the TT forum some are very enthusiastic. therefore my plan was, because I just don’t find a suitable specialist workshop for a total check of my coupés to have a inspection at wimmer. since there are several branches of wimm he gives my question whether one is especially recommended or not recommended by anyone!?? which is the “original workshop”? or what do you think my idea to entrust my audio whimmer to?
