I've had the Viper for a few days now and not sure if the virbrating noise by the door sill is normal (?). The noise is coming from the driver side, not too far from the hood and i don't hear it shakes or rattle all the time. I can't really describe the sound, maybe "rattle" might be a better choice of word. Maybe it's b/c i didn't close the hood properly? I'm pretty sure that i closed the hood properly (read the manual, watched the tape and read "closing the hood" in the archives). My apologies if i'm not doing a good job of describing this. Any thoughts on this would very much be appreciated. Thank you. I forgot to add that this is a 2002 GTS.
