Performance mods for 2000 S430
 

Interested in getting some recommendations on adding performance to my 2000 s430. Car is stock. Thanks in advance.

A lot of tuners sell stuff for your car, in my experience the most bang for your buck comes from a kleeman supercharger.-

I have never found any modifications that are more bang for the buck than trading it in on a 500. The numbers aren't staggeringly different, but the two cars are night and day to drive. With depreciation, the cost difference between a 430 and a 500 is minimal.
