I am new to the forum. Back in the '70s and '80s I was a tech at a Chevy dealer. Never owned a Corvette but will be in the next month. I am wondering what the best choice is from what I have seen in the last few days. Looking at a 2007 ZO6 or 2014-2018 non-ZO6, manual trans, Z51 package. Any guidance would be appreciated. Thanks.
