I live in Austin, and the Ducati Austin dealership is top notch. Very approachable people. Vito and his wife talked to me for quite some time about all sorts of things. I bought my tracksuit, tire install, and some other knick knacks.
However, I bought a V4S from V1 in Houston because they had a Corse that I wanted. They are awesome, too! Seems like they carry more inventory than Austin. They definitely make a "brotherhood" type feeling. If I lived in Houston, I would definitely go out on their scheduled rides. Their tech caught a rookie mistake I made with installation of my rear sets. He was kind enough to not make fun of the situation and remedied the problem. They consigned my BMW K1600b and took a flat rate for helping me sell it. Communication has been top notch.
My guess is that you can't go wrong with either.
