After a while of cold weather I hear a belt squeal on start up.
Yesterday the Porsche dealer in my area did a top to bottom inspection of everything and other than a wheel alignment found nothing wrong.
I asked about the squeal and a very raspy uneven exhaust sound
he said "when its below freezing it just makes noises that it doesn't when its warm,nothing unusual"
I guess I'll have to take his word for it, one the best dealer service departments in the northeast.
A McLaren SLR pulled into the hangar sized garage and the attendant told me the dealership was getting two of the four that were being imported in the US.
