I have a full description at: https://sites.google.com/site/atikovi2015/home/2006-lincoln-town-car-signature-l priced at $5,995 and it's on Ebay at: http://www.ebay.com/itm/Lincoln-Town-Car-Signature-L-Limousine-/151665609641?ssPageName=STRK:MESE:IT if you want to get it a little cheaper.
That is damn steep. I usually hit the import show and it's just $20 which is still pretty high when a regular car show entry anywhere in the country is $10 to $15. I went a few years ago at the last minute and they charged $75. Oh well.
