Thanks for the replies.

I'm not sure do I want a full on project or something that just needs a bit of sprucing up. It'll only be an occasional car, although that could change. I was considering getting a 318i and sticking an m44 into it, just to have something a bit different. On the other hand, I saw a green 323i in meath that looks very nice and seems to be something I could get in and drive without too much of a fuss.

A few questions I was mulling over:

Is there anyone in Ireland who can replace a roof? Or a rear window?
Is scuttle shake bad on them?
