I have a BMW E30 320is as a daily hack at the moment, and was wondering is
it worth hanging onto when it's no longer required (soon-ish). Picked it up
for silly money, really nice condition, etc., etc. Are these rare? Haven't
seen any others for sale trawling the net, just the odd 318is.

Wouldn't want to let this one get away if it were a "keeper", like most
people I've let cars go before that I would kill for now.
