Mine started doing the same thing Jan07, then I found that as the weather warmed up it disappeared, and this winter it hasn't come back at all. (tho car not used daily like it was before)
Spoke to a couple of people at the time and it is the case that it isn't disengaging as quick as it should, but also said that it's very common and doesn't cause any problems - just as well too as it's a small fortune to change the starter motor!!
It isn't a problem - car starts fine its just a bit annoying.Makes it sound like a bit of an old banger. Might have to have a fiddle with it over the weekend check its all oiled/greased properly etc...
Otherwise I hope it gets warm soon and cures the problem
yeah, I did find it a bit embarrasing getting into such a lovely car then it making such an awful noise.
I got the impression that the starter motor is pretty inaccessable - that the engine/clutch has to be moved to get to it!
