I have an 04 C5 Z51 package, ArcticWhite. I passed on the Z06 for the same reason, I had to have the removable top. I test drove a C6 too and I nearly drove it home. But I resisted. I got a great deal on my 04 when I bought it last summer. Plus I hear the 06 and 07 may have some nice options like a 6 speed auto.
