I thought I'd better post some photos of my recently purchased 320Ci after I gave it a good clean! It's a 2001 model in black sapphire metallic with beige leather and a myrtle wood trim.
Since taking the photos I have installed a new head unit (Pioneer DEH-X9500BT) with centre mount fascia, swapped the trays in the centre console for cup holders, replaced the missing rear reflector and put in some (black) floor mats. I just need to get some replacement M badges which are missing from some of the wheels, and do something to the few small scuffs on the bumpers. At a later date I might swap the current wheels for some genuine MV2s, as the current replicas are a bit scuffed/kerbed (or I might just get them refurbished if cheap enough!)
