Thats an Audi A6 on the home page (basically a VW)
I've lived in the PGH area most of my life, been to just about every VW dealer, am now on my 12 VW in the past 20 years.
I used to work at 3 Rivers as well. There is a new dealer in the South Hills, Cochran VW (where the Saturn dealer used to be), corner of West Liberty Ave and Pioneer.
A good friend of mine is a mechanic there. I've been there a few times and always have him work on my car, so far I have had a great experience with the dealership.
I also have a good friend who has his own shop, was a VW dealer mechanic for many years and has also worked on a lot of my cars. His shop is a bit far from you, but he does great work and is reasonable with price. He only works on VW/ Audi auto's and does repairs, maintenance and performance.
It's called German Auto Outfitters, 50 South Street Beallsville, PA 15313 - (724) 632-5866.
