I have an SIV hard top that is probably typical condition for a Michigan top. Windows are intact but fogged. Most of the rubber is hard. The rear window stainless trim is missing. It has a good headliner. There is rust inside under the rear window but no rust through on the exterior. It could be used as is but needs a restoration. I've been offered $250 trade value. Is this fair or would I be better off selling it outright? I've seen tops on ebay with high reserves but I don't know what they are actually selling for.
