Or just monotone the bumpers and side cladding which looks very good ont he older cars as well as the newer ones.
I think the side mouldings are just clipped on so removing them probably wouldn't be too hard if you went very slowly and did not bend them much.
If you are selling the car, JCE's advice is very good, keep it all original.
If you are keeping the car, then I would suggest monotoning it, swap the interior if you want, and do some good mechanical upgrades to give it that extra oompf.
