For anyone looking for a C6, or related parts, take a peek at what is up for auction on Bring A Trailer (bringatrailer.com). Enter Corvette C6 in the search window to zero in on the C6s or click on the links below.
I would like it to be known that I do not endorse Bring A Trailer and I do not benefit in any way from posting the links below. It's just fun to look at all the different vehicles, especially Corvettes, that pass through. BaT is one of many, many outlets for buying and selling vehicles. Vehicle prices vary greatly across all the available outlets so do your homework before bidding/purchasing to insure you get a price that you are comfortable with.

Don't forget to add another 5% to the sales price to cover the buyers fee.
Also, depending on location of the vehicle you may incur considerable cost to get it home.
As you noted that's one of the parameters for doing your homework.
