Find Audi Dealers in Buffalo, New York

Hi, I am looking for some advice. My local Audi dealer in Buffalo is pretty bad and has had nothing but bad words abound by friends and co-workers. I went there looking for a A4 Cabrio (For Lease or possible purchase of a pre-owned) and they had none. The salespeople did not even seem very enthused to offer me any info or point me toward another car. Very disappointed. So I went to Rochester, NY and found a nice 2005 Cabrio with 18K miles but not certified (Sticker was 32k got dealer down to 28k).. I found comparable cars which were certified for 27-28k at other dealers much further away. I want to take advantage of the .9% financing on a 2005/6... but $2500 extra is what it would take! Yuk. So, now the $479/$499 A4 Cabrio lease deals are here, and I would like to get a new A4 Quattro 2.0 (or 3.2) with NAV. And I am apprehensive about both dealers I have went to because they seemed like it would be a hardship to even look for a car that fit the lease deal (and the Rochester one did plead ignorance to the lease deal in the first place). Now I know there seem to be few Cabs in this area, what would be my best bet to find a lease or purchase vehicle? Any recommended dealers in the Northeast?

A reputable dealership in Buffalo NY offered to sell me a 2000 A6 2.7T for 15000 before tax. The car has 64,000 miles on it. They claimed to have had an oil leak fixed (2400$) at the Audi dealership prior to selling me the car. And they told me the brakes may need to be replaced soon although they pass New York State inspection for now. I had the car evaluated by my own mechanic (they werent expecting this), and he told me 1) the turbos were still covered in oil (actively leaking vs just not cleaned off), 2) front brakes need to be replaced, 3) check engine light just came on. If the dealership addresses all these problems do you suppose its a good deal. Or does it sound like the car is going to cause more trouble. I loved driving the A6 and although I can get a newer A4 for the same price, its just not quite the same feeling...... Comments, Suggestions..?
