I know this still doesn't answer your question about consignment selling but I also agree that you could probably sell it remotely, especially if it is in good condition. So many people buy their Lotus long distance that a lot of good photos, verifiable records, and (most importantly) good communication go a long way.
Both me and my son bought our cars (an Elise and an Exige) remotely from California, and we live in Wisconsin. It was never necessary to touch the cars as long as we had really good and honest communication. Both cars were delivered exactly as represented.
