I would like to buy a bellypan
 

If anyone wants to make be out of plastic for a corolla, I would buy one. Same with a decent looking grille block

What fun is there in that? Plus shipping large pieces would be $$....Just get some chloroplast and start from the front bumper chin to the radiator support as a first step. Probably take you 15 mins once you got all your scissors and zip ties together...
