I have a 98' 3.2 I love it. But Ever since I got it the left back wheel makes this metalish noise when ever the car starts moving. When ever I have my window down I can hear the noise and it's annoying the crap out of me, could someone please help me as to what could be the problem.

 

i'm guess it might be your brake pads. the brake pads have a indicator on. the indicator is a peice of metal that slightly scraps the rotors to let the driver know that their pads need to be replaced.

 

I had the same problem on my front passanger breaks... it was this little small metal thing that was broken in half... Took it to Midas and they fixed it for about $600.00, but i had them do both front brakes and the rear. Now i just take advantage of the "Lifetime" thing they have... just take it back and they fix it free...lol...
