Hi dabs. No sunroof fitted. I dont think it's door seals as they look to be in fairly good shape. Not sure about the round bungs, but will take another look at those today. If I remember correctly when I was checking out the exhaust last time I did have a look at other stuff under it. The bungs looked to be covered in underseal but will recheck. I've got a horrible feeling that I'm going to have to take out the passenger seat, glove box and pull back the carpet. As for wheel arches i dont think its a problem so much when driving but when parked facing up hill outside my house, the car was stationary for two days then when i got in i checked and there it was. Job for the weekend I think. Cheers guys will keep you posted.
