Wow my local 'do it yourself' junkyards don't / wont carry MDXs. Probably because the parts are worth too much.I've seen the replacement covers on eBay. Mine is pretty messed up but I've seen good to decent second hand ones going for the same or even a little less at a wrecker. I'm not sure it's worth the effort to recover mine when I can accomplish almost the same thing with a screwdriver and 5 minutes.
Oh I know about that site, just the poster made it sound like you can go to a 'pickapart' and none of those near me (I have 3) will ever carry a high end car like the MDX. Those junk yards will sell you the part , for a nice premium.Check ebay for second hand parts or else car-part(dot)com. I bet you there's an MDX in a yard not far from you. I have my choice of about 10 within an hour's drive.
