That's the answer my local Toyota parts guy told me. A new under cover is a bit over $450. ordering from Toyota. Mine came off in 2009 & was put back on by a co-worker & lasted till I hit something on the freeway last week & was dragged till I could get stopped. I'm getting one from the owner of a wrecked mr2. $450+ is ridiculous for formed plastic.I would say to help stop something from bouncing up of the road and hitting the engine.
