The other thing I am distrustful of is a new front bumper, and the obvious grille change. I get if you like the grille, but have you ever had to change out a front bumper on a hot rod truck for no reason? Not a rust issue or the back bumper would have been changed as well.
As for the price that high for the options- that only works out if all those things are exactly what you are going to put on. Its not lie you can pull them off and sale them used for enough $ to make up for it.
