Manual or Auto?
#21
The 6 speed auto in the C6 has been a headache from day one. There are many other reasons to buy a C6 besides the 6 speed auto. If I was corvette shopping and didn't have the cash for a C6 Z06, I would buy an 08+ base model C6 M6 car. Then if I wanted an auto I would buy the same car and have it converted to a 4L65e.
The LS2 is still a great motor to start with, the car is cheaper to buy and is also obviously already set up to accept the more 'mod friendly' 4 speed auto.

If I were building a fast/consistent street/strip car right now it would either be an automatic C5 or automatic 2005 C6.

The electrical issues are not necessarily going to be a concern on every single 2005, it's generally a hit or miss situation there.
I only suggest it for those seeking an automatic that they're going to build for strip duty...if one was staying stock or choosing a manual trans then I would definitely recommend a 2006 or later.
