We spent quality time on freeways, around town and on challenging two-lanes in both base V6 and top-line V8 CXS Lucernes and found much to like and little to criticize....
... The standard car allows relatively spirited driving (more aggressive than its buyers will likely attempt) with adequate power, good control and solid braking. Only its ultra-light power steering disappointed us, yet it might please typical buyers.
The V8-powered CXS would be our choice for its full complement of features and outstanding ride and handling although its magnetic power steering also struck us as a bit light and devoid of feel. Especially impressive were the unusually low noise levels inside both cabins, thanks to Buick's standard QuietTuning.
