ah, I know what you're talking about then... kinda like a shade that you lay horizontally so no one sees the junk in your trunk..
I've only had my supra for a month, of which time I got to enjoy driving for two weeks before the fuel system? has kept her parked for the remaining time, but so far I've just kept my back seats folded down and my trunk empty.. I'm certain tho, once I get a deck and speakers installed, I'll wanna do subs and an amp... at which point I will most like opt to spend this $300 as well, unless I can find a local upholester that can do it cheaper..
