GS430 all day long. Had both (S16) and the 430 is better in every way. There wasn’t a lot in it from a fuel consumption perspective, but performance was so much better. With the custom exhaust on the 430, the exhaust note was great too. Only thing I preferred on the 300 Sport over the 430 Sport, was the colour. The dark metallic blue was much more eye catching than silver. I also ran the Gen1 Sport wheels on both of the S16’s, they looked great on the Gen2 as well.
