I was looking at the roof of my car (2001 gt) tonight after i pulled into the gas station for a fill up and noticed that on the passenger side right above the rear quarter window there is a fair amount of rust visible. It is on the roof comming from under the trim piece that goes around the outside of the window. From what I can tell it is only on the passenger side...is this something I should be concerned about? or is it common for these cars to get rust here...any info would be greatly appreciated Thanks!!!

It also is looking like the driver's side might have a little bit developing also
