Well, I was toying with this idea since the xB came to our market. An "Escalade" type of looking vehicle, either with a removeable back cab part, or a slide down rear window, build off the RAV 4 4WD platform, but lower to the ground. I think would make a nice replacement for the xB. Heh heh, the xE (wouldn't bee the xD because the xA would need to be the first replacement). As for the xA replacement, I think that the continuation of the 4 door lift back in a sub compact vehicle would still be strong, but built on a Yaris or Corolla platform, use the 1.8, but make it more like a 4 door coupe liftback, similar to the tC but blending an xA and tC look. I'll do some scetches and post them as soon as possible.
