There are plenty of flaws in the 135i but they are all minor. The 135i was never meant to be an all out sports car, it's a 1 series equipped with the M sport package with a bloody fantastic engine. Floaty suspension, RFT's, lack of LSD, louder exhaust etc - they are all things the ///1M will deliver.
The 2 things I'd like to see fixed in the next gen 135i are the HPFP and possibly easier ECU access! lol
