04 MC40 w/5K Miles value?
 

My elderly father in law is considering selling his 2004 Mini Cooper S Monte Carlo 40th Anniv Edition that he bought new and driven only 5K miles. It has been properly stored in his So Cal garage since new. Since the Kelly Blue book only reflects like $4-6K, I’m reaching out to this knowledgeable crowd to try and get a grasp on the real world value. Please give me your thoughts. It is 100% original and other than needing a good detailing due to a lack of use, its in excellent condition with all the goofy stickers, paperwork, window sticker etc....
