Hi rabmc,
Have a look on here for some info : bm3w.co.uk
I have some good links at work to buying guides etc, give me a nudge on Monday and I will post them up.
Theirs a few of us on here with both evo and non evo versions.
If you can find one with warranty its a very good idea - mines recently just had a full top end rebuild due to a snapped camshaft
If the price is right I would sell mine - 1998 (r plate), 57k, full BMWSH, BMW extendable warranty, BMW CD, heated seats etc. All standard apart from a ACS pipe, pm me if your interested.
Cheers,
WD
