Know what? The problem wasn't the seatbelt. The same friend rode with me last night and without fail when I drove over a freeway's lane change bumps the rattle makes itself known -- and very loudly. I may try to find those screws that another post mentioned. He said the rattle is coming from behind the passenger seat at about shoulder level. I'll check it out this weekend.

This is all kind of annoying with only 1550 miles on the odometer...

 

well, glad to hear you figured out what it was... sorry to hear it isn't something simple like the seatbelt... i can definitely see that it is annoying given yours is just a baby... you could always just do what i do... turn the volume up.

but seriously -- i really have very few rattles in the car. outside of just some (what i would consider normal) chatter when i run over railroad tracks and stuff... the car's very tight... *shrug* hope you get it fixed easily...
