Just been to Smiths of Bloxham (Near Banbury) to get something for my touring and saw they have a 2 door e30 with sports seats. They seemed in very good condition and the mechanisms worked fine etc., except for a poor repair on the drivers bolster. (No rear headrests)
Took a couple of photos on my phone for anyone who may be interested:
Its just boken glass on the seat base
Hope this helps someone.
