I love this product. Like the others have mentioned, if you weren't looking for it, you would not notice the subtle difference. The fit and finish make it look like OEM. I did not have to do very much shimming, all the bolt holes just seemed to line up with little "persuasion". The sheet metal on these things are considerably thicker (14 gauge) than the factory sheet metal.
If you do not have your own painting tools, expect to drop another $500 to $800 to have it professionally painted.
If you are clever enough, you could alter your stock fenders and cut the hood to achieve the same result for next to nothing, but you are going to have to be pretty talented if it is going to look clean and not cobbled together. Also, all of the under the hood components will readily fit like stock without any shifting around on the AEV highline.
I can guarantee, that if you are willing to drop the coin, you will get a quality looking highline with an equivalent 2.5" of additional tire clearance with no lift.
