Yup, a 1989 325i.  Plastic bumpers, 14" cross-spokes, Alpine Weiss.  I can't
quite make out if it has a boot spoiler, and it's hard to tell if there's an
'iS' lip spoiler, but then it would be a surprise if the original 'iS' lip
spoiler was still present on the car.  I'm going to guess that it is a
325is, as I haven't seen many 325i models with the cross-spoke alloys.  And
it surely can't be an 'eta' as didn't they cease production before the
switch to plastic bumpers?
