I bought a Scion xB from these guys, and the process was fairly hassle free. There's no haggling on Scions, so the process is fairly simple and straight-forward. There was no pressure, things went smoothly. The inventory on the xB was a little low, but they had the color I wanted so I lucked out. You may want to call in advance to see what they have. They didn't really push much feature wise on me, other than some paint-protection package, which I declined (since my vehicle stays in a parking garage most of the day.)
It doesn't get much simpler than this, when it comes to Scion buying.
