I use the website supercarros.com to look for used cars to buy in the Dominican Republic but they do not have a 2003 Hyundai Tiburon in their database. Do you know of any other websites in Santo Domingo or in the Dominican Republic that might have that particular car listed? Suppercarros.com seems to be one of the best websites to look for a particular used car in the Dominican Republic. There might be other websites but I do not know of them at this point.
