I'm feeling a bit old now. I just noticed on realoem and bmwfans that the e36 has moved out of the mainstream parts catalogue in to the "mobile tradition" one, meaning that it's now a classic car officially in BMW's eyes.

I'm not sure what it means in terms of parts availability or pricing, etc. But it definitely means the e36 is now an old car.
