How to figure a price

Haven't been on in while but was when the '64 Dart GT convert restoration was going on. Have really enjoyed the experience of driving what I drove in the first half of the 70s... very nostalgic!! That car was recreated exactly. But it was not meant to be an always and forever thing, and I'm in a dense inner suburb where really getting this out for a drive is hard. So probably time to sell it.

Still I don't have a clue on how to price something like this. Clearly since I paid for restoration it will be far from break even -- but I knew that going in. Are any of the classic car sites better than others. There appears to be an aggregator that puts it around on lots of sites. Checked them out ... prices are all over the place. What have others done?
