I have a stick - on one on my HEVAC. I thought it was proper wood, (was on another unit) and had me fooled until I actually went to swap the front panel over and I saw it was stick on plastic. Given the rest of my Vogue has the real stuff, the difference between the 2 isn't that noticeable, especially on the HEVAC as it's a bit hidden away!
The real vogue/autobiography stuff goes for silly money... Just watch out on eBay though as there are a couple of sellers I've found which are selling walnut items, which were never done as standard and selling them for a LOT of money - when looking into it some more, it's actually just a water print transfer, NOT real walnut veneer.
