Need to talk to car nuts whom one trusts who buy relevant new S/CL/SL63/65 frequently, e.g., every 6-12mos, to have better anecdotal data....
Need to assess (via common-sense engineering and real-world driving analysis) active/passive safety of various cars....
And place own bets...
Based upon my amateur analysis, have never been impressed w/overall active/passive safety of any car on planet vs curr-gen S/CL63/65....
Based upon anecdotal feedback and own expce, doubt any car on planet today has better quality/reliability than curr-gen S/CL....
IMO, part of what's fun/intellectually interesting re: cars is that full data set is unavailable re: any car....need to place own bets based upon common-sense analysis/judgment; anecdotal feedback; and own driving impressions....those who can't successfully manage this bet prob aren't particularly sharp anyway and also struggle w/most risk/reward bets in their career/life generally.....Darwinian selection often prevails.....after all, where/when else in US is an affluent guy more at physical risk (and instantaneous decision-making risk, based upon driving judgment/skills and active safety tech) than in his daily commute???....
