Yeah, it gets a bit ridiculous with people asking over 250 for a grill and over 600 for a bonnet.
When you consider the number of peolpe with 32's that would want a gtr style hood and grill, there should be a package for 500 that includes replicas of the two, and the necessary bits and pieces to modify bonnet latch.
Could even add another 300 and include a front bar, or go for a grand and include painting and fitting - so it's essentially a changeover, and you lose your GTS-T front bar and hood in return for a GTR style hood, grill and front bar.
For a grand, I'd probably do it...
