OMG! Tell me about it! Had things been different and I actually has some say in the purchase of our family sedan I would likely be all over the ATS, but it was my wife's decision and we are now 328i owners. I Like the car, but the cost of aftermarket is just stupid and honestly my wife and I argue over who drives the 2007 SKY more than the 2012 328i..

My only concerns is with the overall strength of the new motor. Some GM docs show the rods as Forged powdered metal vs. Forged Steel. I suspect the initial data is for the 2.5L motor, but the 2.0L has forged steel like is the case with the LE5(2.4>) vs LNF(2.0L).
Also on the GMpowertrain.com shows an image of the new engine and you can see in fact it does have a blue canister filter near the exhaust manifold at the bottom of the engine. Also if I can find it somewhere I saw that the Modular balance shaft system was in oil pan rather than part of the main block like the rest of the ECOTEC blocks.
