This paper presents a web application which improves the usability of a fuzzy retrieval system for purchasing cars. The aim of this system is to support such persons who are not good with machines or cars when they select a car. Unspecific conditions are expressed by the fuzzy set, and the level matching conditions are expressed by the grade values. To use this more practically, a GUI form with selection menus is developed. In addition, employing the self-organizing maps performs clustering and visualization of the result (obtained from the fuzzy retrieval system) in order to improve the accuracy of decision making.
