I agree with the others on price. One factor to consider is the pending release of the C6 Z06 price (some day....). It will be interesting to see what type of impact the C6 Z price has on the C5 market. If the C6 Z is priced high ($70k), nothing much will happen. If it's priced close to $60k I think that the market will see another flood of C5 Z06's, thus driving down the value of yours. Purely speculation on my part, but wanted to chime in.
