Corvette Performance - Older C6s

I was looking at a 05 3LT with 100k miles price is right. What are the problems with the 05 the rearend but the rearend sucks in an f-body too. I read something about the auto trans being not so great but don't remember. I know i can get C5Z for about the same price but I want a C6.

06 differential has extra ribs for strengthing that the 05 does not. The 05 also has a 4 speed automatic vs. a 6 speed for 06+.

100K is a lot of miles but if taken care of and maintained properly might be a pretty good car. Particularly if most of the miles are highway. How many miles are on the C5Z?

64k on the Z

I would probably save up a little more and get an 06+ will less miles.

Many Corvette owners baby their cars. It should be fairly easy to find one with less miles.

Another vote for the 06+, for the rear end at the 6l80 instead of the 4l65. I have an 07 Z and have had zero issues what so ever.

The C5Z will crush the C6 LS2 in every aspect of performance FYI....
