if you make the best of the local attractions while you're there, then it's well worth it! Did you buy it in the Twin Cities? Lot's going on this weekend! AMA Supercross. The Car Show. etc
Even without that, it's worth the trip. Since you just got the car and there's only a 30 day warranty on it, it might be good to get her out on the open road and see if any other troubles surface.
For the record. My '04 had a slight squeak to it until it warmed up starting around December or early January. Here I sit about 2 months later and I'm emabarrased at how constant and noisy it is. The other day I was driving home at 50 MPH and I could hear it over KFAN. Needless to say I turned it to a rock station and increased the volume level. That magically got rid of the center console rattle, too!
