I understand the sentiment for those other cars because of cosmetics, family reasons and interior luxury etc. However based on performance and driving dynamics , I am not sure any of them could live with M5CS. Please see some of the videos below. M5CS is regarded as the best super sedan currently on sale. All reviews so far have been superlative and show that it rides and feels different to M5Comp. If I have the money, it is the only car I would change my M6GCComp for. Please don't take offence with me. Thanks
