Thanks for the replies everyone.
I am no longer concerned about the wood, as finding a clean 330 ZSP with the 6-speed manual is hard enough. I might need to start considering 325s because of financial reasons.
I do know that the wood is real (at least it was real on my E36 M3 w/ Luxury Package).
Also, wood trim does not distinguish a car as either sports or luxury. There are many objectively defined sports cars that can be ordered with wood trim. Even though E46s are entry level luxury cars, I also consider them sport sedans, coupes, etc.
