I live in Pittsburgh, PA. I am a new member to the Ferrari Forum (I do not currently have a Ferrari) and I am a car fanatic. I currently drive a Mercedes Benz CLK430 and a past owner of several corvettes including most recently an '01 ZO6.
The white testerossa you mentioned may belong to a kid a went to high school with. They have a Ferrari and a Lamborghini Countach along with some other toys. I have a few other friends in the area that also own Ferrari's. We do sometimes get together for cruises and to go to car shows.
There is an open car show every Sunday near the Pittsburgh airport where people from all over get together discuss cars and show off their pride and joys. Everything from, classics, to Vipers, Ferrari's, luxury modes, and turner cars. Let me know if you are interested and I will let you know the next time we go.
