That rear spoiler on the Z-51's looked like it was glued on by a monkey!!!!
The rear Conv. was Charcoal Grey, which is the color and model my son is considering.
I think the way to go is to pick up a used 2013 427 Conv... Better looking and should hold it's value if purchased for around $60.K Or... get a 2008+ LS3 and mod the crap out of it!!!!
