All of the above having been said, an unmodified 135i has more than enough power and acceleration for any conceivable street use. The exhaust note of a 135is is probably better than that from a 1M, for aficionados of that sort of thing. Just doing a PPK flash does improve the exhaust note of a stock 135i, but it's nowhere near as good as on the "is." The EPS on most new BMWs sucks in comparison to that on any E82/E88 1-Series vehicle. The EPS on the M2 is better, and probably "more precise" than on a 1-Series car, however the feedback to the driver is pretty mediocre nonetheless.
