I hope you Pittsburgh folks have better luck than I did with Mazda dealerships. I bought from Monroeville Mazda in Aug 2013, and they dropped the mazda franchise at the end of December. (They didn't sell the franchise - it actually reverted back to Mazda.)
So, I started doing my service visits at what used to be Baierl (or something like that) Mazda, but that changed to Cochran Mazda (north hills/wexford), and now it looks like Cochran is dropping the franchise as well. They've torn down the showroom building, but claim they still have the franchise working out the VW showroom... Yet, when I ask a non-salesperson directly, I get a very evasive answer on what they are planning to do.
If Cochran disappears, I honestly don't know where I'll end up going for service/repairs... I think the next closest mazda dealership to my home/work is up in Butler.
