I noticed the buyer on the Coronet only had 10 feedback points. It's a 'wait-and-see' about whether he pays up.
Another idea could be that the guy has a 1:1 '68 Coronet in his heated garage, and wanted a pristine kit to display with it at the local car show.
I have a 1:1 Imperial Crown convertible, previously owned by Sally Anne Howse, of Chitty Chitty Bang Bang fame. I have watched for a nice, unbuilt kit of the flying car from the movie since 1998, but I still wouldn't pay $1100 for it! LOL
