I think one of the best measures of performance is how a dealer/service department responds, when an unusual issue crops up. Sommer's Subaru excel in this regard. I recently had an issue with intermittent power steering on startup. Sommer's service department took the time to find the root cause and fix it, asking for help from the tech line and Engineering as needed. I was able to use a loaner car during the repair, and of course it was fixed under warranty. The 2016 Impreza is my 3rd Subaru bought or leased from Sommer's. Though problems have been relatively rare in general, Sommer's have gone out of their way not only to make effective repairs, but also to ensure customer satisfaction. I recommend them highly for Service (and Sales).
