The S is the sport version.
It has the M-Tech suspension (lower springs),different gearbox ratio (slightly
lower) and a 25% limited slip differential (better in slippery conditions)
Engines are identical.
There a also a few standard interior add-ons ( see below) of which you can get
most in a "plain" 325i. One he misted is the OBC (on board Computer)
