I bought my '11 vert on July 1, 2011, we loved it. I did have the top replaced in April of 2012 for wear marks, the dealer did a great job.........can't say enough good things about them! Never experienced another problem with the top after that, no leaks, no wear marks, nothing.
After over 18,000 miles I decided that the L99 was boring so traded it for a 2013 LS3, at just over 1600 miles we are loving it. Looked at a coupe w/ sun roof but it just wasn't the same. Top down is a great way to go.
