I think that if you look at the original sheet metal you will see that the feature line is not that sharp. It's the shadow line that this creates that makes it look sharper than it is. That area was not a problem for me on the full quarters. The scallop area (lower front rear quarter) is slightly off on both sides so you need to cut the quarter to get it to line up. The belt line (top of the quarter, 90 degree bend) is blunted on the passenger side, the trunk drop-off toward the gutter is too shallow needing cut to raise up, and the front top of the passenger side quarter curves in sharply and needs cut to be straigtenend. A good body man could fix all this (I once was one and owned a shop) but why pay one to unnecessarily? All my metal was butt welded in and you cannot tell from the inside that the quarters were replaced. There's also the issue of alignment. If the factory sheet metal is lined up well (i.e., door gap, trunk gap) why monkey with it using aftermarket sheetmetal. We had to do some major gymnastics to get my trunk gap presentable. I'm very picky and too 99% of the people it looks just fine, but if I could've avoided it, I would've.
