The latest Sport Nav + models are fitted with a newer style 18 inch wheel finished in a polished gunmetal paint / laquer finish that isn't diamond cut. It looks similar but not the same as the 152 style shown in the above photo. Diamond cut wheels look good but deteriorate quickly even with regular TLC. Glad Mazda dropped them for the latest model.
