Dorschel Automotive Group at 3817 West Henrietta Road, Rochester, New York.

I've purchased two brand new cars from Dorschel and been relatively happy with their staff, but my father recently went in to buy a van from them and was treated very poorly by the sales staff. I probably won't be buying a third car here.

Update:
My father ended up buying a utility van that he saw twice at night (in the dark) and found out it had a broken panel when he got it home in daylight. Dorschel's response thus far is basically "too bad, you bought it." Great sales tactics.
