For anyone looking for a C4, or related parts, take a peek at what is up for auction on Bring A Trailer by clicking on this link (bringatrailer.com). If you're interested in other generations of Corvettes check out this thread.
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 above. It's just fun to look at all the different vehicles, especially Corvettes, that pass through. BaT is just 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.
