What year is your Grand Marquis and is it an LS model ? I have a similar car mine being a 1989 Grand Marquis LS 50th Anniversary Edition in dark blue metallic clearcoat with full cloth carriage roof and all exterior trim in gold anodized with trunk mounted luggage rack. This car had only 67,000.0 miles when purchased in January of 2022. According to a plaque on the dashboard it is one of only 250 built with this trim package.
