A 97 323i sport went up on gumtree.co.uk in Belfast last night for £550. I can't find the ad so it could be sold. There's a 328i touring on Gumtree Belfast for 600p
I don't think you will get a donor car down south with decent running gear for under a bag a sand.

If you were prepared to go to uk you could expect to get something like this

Sold for 900
