When I got the car I didn't even know about the missing trim, I have been hunting it down and finally got 2 c-pillar trim sets and clear toyota visors! (they were in terrible condition though) I am going to post a thread on how I repaired the two I got.

Anyway, my MR2 still has a 4-age that was rebuilt and according to my neighbor, swapped from a camry or corolla. I have a aftermarket exhaust that is tucked right under the bumper / right corner.
