I think one of the big things why some of these molded front fascias look weird, is because they not longer keep the stock bodylines of the doors, fenders, and sideskirts. Without them, the front fascia looks like an after thought.
Thats one of the reasons why the molded svt fascia looks so good. Keeps the stock bodylines. Same thing with the grand prix front end this guy molded. It looks like it came from the factory that way. Not to mention, it has all the right curves.
