Hey, iv used the search, but couldnt find. I was wondering if it was possible to put in wood trim into a 3rd gen Advanced?? and if so would it be a easy take off plastic and put on wood? lol or a big diy job

Sure is, just finding it at a wreckers can be a little difficult, and Mitsu very expensive.

Theres a few alternatives to replacing your dash trim discussed in this here thread:
