I already had one rattle behind me fixed...the headliner would vibrate like a rattlesnake when I was up to speed. This began when the car had a mere 600 miles on it. I wound up having to replace the headliner altogether...imagine having the entire (upper) interior of your car being torn out and replaced just four weeks after you got it, with only a few hundred miles on it! Grrr....

Oh well, at least it's fixed and I must admit they did an excellent job; you can't tell anything was ever touched inside the car at all.
