t2p, yeah, let me clarify, IMHO, a CR-V is a "tall wagon", like a Rav-4 or Ford Escape: no frame, 4cyl/ FWD available. A Lexus RX300 or Acura MDX is really more like a minivan, still a transverse mount engine, AWD typical instead of 4wd, independent suspension in the rear.
An SUV to me is anything that sits high, body-on-frame: truck style, and has seats where the bed would be. This includes 4runners, jeep liberty and wrangler, Troopers, Yukons, TrailBlazers, Explorers, etc. (I guess I'll throw in the Grand Cherokee as well, even though it is unique). It would also have a longitude mount engine and a solid rear axle.
A VX? In a class by itself. ;-)
