I know I'm definitely "new in town", but did want to share this. If it's already been discussed, then my apologies. To solve the issue of rear visability (or lack thereof) I took the rear head rests out, added convex mirrors to the side mirrors and mounted an optical lens on the rear window. The lens is just a piece of flexible plastic with concentric rings that gives you a wide-angle (up and down - side to side) view out your rear window. I can't take credit for this idea - saw it in a VX review online while I was shopping around for a new vehicle. The usual auto part stores in my area did not stock this item. However, my folks are RV enthusiasts from the old days and they suggested an RV dealership. Sure enough - I stopped by yesterday and they had a few. They're made by 3M under the brand name Vangard and come in several diffrent sizes. The 8"x10" fits perfectly in the narrowest portion (center) of the rear window. Wet it, stick it to the window and it will dry clear in 24 hours and stays until you peel it off. According to the manufacturer, it should not be effected by factory defrost (after-market defrost installs may be a different story). And I can tell you it makes a big difference. I can now see the ground behind my VX instead of just a slice of blue sky.
