Agreed, it&#x27;s mostly fit and finish. Truth, if we only look at on road performance the CTS&#x2F;ATS probably beat the 3 series. But the interior of a BMW is just leaps and bounds above the cheap feel of the Cadillac.<p>Source, daily driver is a 2013 3 Series and my brother is one of the engineers doing NVH testing on the CTS&#x2F;ATS, we compare notes frequently. And, as part of his job he did have to test the other vehicles in the class.<p>Honestly, after a relocation I can&#x27;t really justify the cost of the BMW so when my lease is up I&#x27;m going to be REALLY sad to get rid of it, nothing else seems to really come close.
