Its an upspec model and is really quite rare.
It had things like different upholstery, fold down rear arm rest, pockets on the door trims, wooden door cappings and a wooden panel behind the ashtray. Also front seat head restraints and leather trimmed steering wheel, a dipping rear mirror, inertia reel front safety belts, an intermittent wash wipe and heated rear window.
The above info from the James Taylor and Mike Mcartney book "The BMW 2002 - a comprehensive guide to the classic sporting saloon"
