I think your price is perfect. You have a rare car with a rare sunroof and a Trilogy! I parted with my 2004 SB in 2012 to buy my house and this January I reversed that decision four years later and bought her back +2700 miles and needing a serious detail job. I paid $18K to get mine back home. I'd definitely pay your asking price to add yours to my collection :-)
