I am new to the Buick world so this may be a dumb question. I bought a 72 buick GS in January. Now I am wondering if it is actually a true GS. It has GS Emblems, hood, and grill. But when I decode the VIN it says that it is a Skylark Custom. Was it possible to get a Custom with a GS package, or did someone just go through a lot of effort to make it look like one.
