Because building a BIW from the ground up is cost and time prohibitive for someone who just wants to race showroom stock, AS, or pro-level autocross, and classes like that. Not everyone who goes racing has a full race shop to build a car like that.... a LOT goes into building a BIW....
And a 1LE car can be used on the street as well...
