The Pre-02's Titanium trim was also more vulnerable to finger print corrosion .... i.e. oil from your skin would show up as a slight dark spot after a day or so .... harder to clean.
Much improved for 2002 .... that's BMW for you ... always listening to customer's issues and then taking corrective action (often subtle and unhearalded changes for the better .... ususally that is, except for the 2001 steering boost debacle which was quickly changed for 2002 again).
