I leave my car at dealers to fix my ic hose leak... (they were replaceing pcv valve) original got stuck.. anyhow i was waiting in waiting room for my mom to pick my up when i hear my car..(rumbling noise) then a hard rev and then long burnout!!!! i look outside.. and its my car!!!!!!!!!!! i gave him a hard dirty look then just ignored it.. i figured if i tick the tech guy off, then he will probly fuck my engine up somehow!!
