I had never heard of these... listing says one of 10 made. If so that's pretty impressive. Not sure this will ever be a genuine collector but who knows. Looks clean for the miles anyway and rather cheap transportation. https://milwaukee.craigslist.org/cto/d/rare-04-buick-lesabre-custom/6377399118.html
Matt , They are not Factory cars , In Maryland , American Sun roof added the top, emblems etc , a dealer add-on . I sold Buicks back then and the top was a fiberglass cap glued to the existing roof with the cloth attached . Our cars did not have the port-holes. Bill
