We bought a van from Round Rock Honda (Classic Honda). Their internet sales guy was great and much more willing to deal than the guys at the central Austin Honda place were.
I mention this on every thread on this topic, but it's still relevant.
I bought from Gunn Honda in S.A. They list their final selling price on their internet site. They were very professional and had the lowest price by far. Even if you don't want to make the drive down to work with them, you can use them to price match.
A good friend of mine got the dealership on Koenig to match the price I paid for my 2006 Accord, 4Dr, SE. He and I paid $20K even, brand new.
I worked with a guy named Giddings Brown who I can't recommend enough.
