I was planning to yes, as far as I can gather, the starter motor isn't too awkward to get at and remove completely - although I've not had a proper look at it on the car yet. From there, it's a complete strip down and recondition - most internal parts being renewable through your alfa garage.
I'm basing this on drawings which are on a GTV/Spider parts list CD I have (CD bought on Ebay)and factory manuals (bought from EB Spares).
Once I've figured out exactly what I'm going to do, I'll post again. In the mean time, I can try and get the pics in some format for you to browse if your looking to have a go at it yourself - feeling brave? I know how annoying it is in the morning to hear that unhealthy whirring noise..... however, I think I can live with it for a few weeks until some warmer weather arrives.
Let me know
