The fake wood panels are 3M brand transfer material that is put over the finished body panel. The material is transluscent, so body color under the transfer must be the same as the rest of the body or the rest of the woodgrain panels or the color will be off. The body panels were the same--wood grain or delete---except for the holes for the surround fake wood trim. The ones without wood trim are relatively rare--maybe one in fifty was built without wood trim.
I have a '93 with the stock 350 engine and it has adequate power, even for towing my boat and snowmobile trailer. The '94 and up, however, were much more powerful. I believe the '93 and older models were more reliable and less costly to maintain, as they had a standard distributor, one oxygen sensor, throttle body injection vs. the tuned port injection on later ones. My main aim would be to find one with little or no rust from a climate that allows that.
