I love my 2014 front end on my 2013 ZL1.
Effectively saved over $5K buying the 2013 ZL1 'vert over the 2014 version's color HUD and upgraded LED taillights. That's it. That's what I'd be paying a lot more for the same performance. The 2013 ZL1 is everything the 2014 ZL1 is. If it weren't for the big savings, I'd have ordered a '14. I like the tails on either.
