I give him the benefit of doubt and assume he means ISF.
No way the IS 250 or 350 should be considered, it's a downgrade from the 335xi with MSport.
EDIT: there's actually a IS350 "F-Sport" model coming out that's different from the current IS lineup with F-Sport accessories (the trinkets I was referring to). with 300hp, in this case it is comparable to the 335. The LFA inspired speedo is a need feature, but this car hasn't been given to the press yet for a shakedown, so not sure what to think.
In any case, OP is thinking about upgrading to the M3 or M4, not a lateral move to a 335 equivalent.
