Check out xAteam.com My girl is on there, because she has an xA.
Also, keep in mind that the xA is basically an xB, with a different shell. Just about everything, minus the body, is the same. There's a few distinct differences in and out, but the cars have swappable parts.
Also, go over to Toyotanation.com (I think that's the site) and check their Scion section.
Anyways, wrong site or not, we should cherish the little xA, as it's quite the beast, just like the xB can be.
