LEASING

IM JUST WONDERING ONE THING ABOUT LEASING BEFORE I DO SOMETHING STUPID TO MY LEASE!!!! THINKING ABOUT SLAPPING A SPOILER ON MY I.S. BUT WOULD THAT EFFECT THE LEASE??? I WENT THE LEXUS WEB SITE TO SEE IF I CAN FIND ANYTHING ON LEASING AND CUSTOMIZING THE CAR. BUT ONE THING IS REALLY BOTHERING ME THOUGHT. WHEN I GOT THE CAR THE SALESMAN TOLD ME THAT I CAN PUT ON A SPOILER SO IM REALLY CONFUSED CAUSE SOME OTHA PEEEPS TOLD ME THAT YOU CANT DO ANYTHING TO A LEASED CAR???? ANY LIGHT ON THIS SITUATION WOULD BE A HUGE HELP!!!!!

THANX
