to drive in traffic i would get the smg. that way you can switch over when you want it easy in bumber to bumber traffic and then
when you want to play on the curves then go to s mode. with smg
you have the best of the 2 worlds.
The performance advantage of manual (or SMG) over the power sapping step is huge on the 325. So, go for SMG (being that this is an enthusiast site, and almost everybody will tell you to get what gives the most performance).
